The derivative of a function at a certain point represents the slope of the tangent line to the function's graph at that point.

To find the slope of the tangent line to a function at a given point, you need to calculate the derivative of the function and then evaluate it at that point.

The value of the derivative of a function f(x) at a specific point x = a gives you the rate of change of the function f(x) at that point.

When a function is constant, its derivative is zero. This means the tangent line to the graph is horizontal, as there is no change in the function's value.

The derivative of a linear function is a constant. The derivative represents the constant slope of the line.

The power rule is a shortcut for finding the derivative of functions involving powers of x. To find the derivative of x^n, multiply the coefficient by n, then reduce the power by 1.

The quotient rule helps find the derivative of functions that are expressed as a quotient (one function divided by another).

The chain rule is used to find the derivative of a composite function. It involves finding the derivative of the outer function and the derivative of the inner function, then multiplying them together.

The limits of the function as x approaches 3 from the left and right are negative infinity and 1/6, respectively.

The limit of the function as x approaches -3 from the left is infinity, and the limit as x approaches -3 from the right does not exist.

Express the given logarithmic expression as a single logarithm.

The given logarithmic expression can be simplified to ln(√((x+4)³/x(x³+10))).

The time it takes for the population to reach 300 bacteria is ln(3)/ln(2).

The inverse function of f(x) is f⁻¹(x) = (x-5)³ + 8.

The least amount of fence required is 2√50 feet.

The sum of the absolute maximum (M) and absolute minimum (m) values of f(x) on the interval [0, π] is 4.

The derivative of a function at a specific point can be found using the limit definition. This method involves taking the limit as h approaches 0 of the difference quotient, which represents the average rate of change of the function over a small interval.

Finding the tangent line to a curve at a specific point involves finding the equation of the line that touches the curve at that point and has the same slope as the curve at that point.

The rate of change of a function can be calculated by finding the derivative of the function. The derivative represents the slope of the tangent line at any point on the function's graph.

The integral of a function represents the area under the curve of that function. It can be visualized as the sum of infinitely small rectangles under the curve.

An inflection point is a point on a curve where the concavity changes. It occurs when the second derivative of the function is equal to zero or undefined.

Concavity refers to the direction in which a curve opens. A curve is concave upward if it opens upward, and it is concave downward if it opens downward.

A function is increasing if its value increases as the input value increases. It is decreasing if its value decreases as the input value increases.

A property of definite integrals where the integral of a constant multiple of a function is equal to the constant multiplied by the integral of the function. In essence, you can factor out a constant from the integral.

The limit of a function as x approaches infinity. This concept helps determine the behavior of a function as its input grows indefinitely large.

A special case of limits where the expression becomes unbounded (either positive or negative infinity) as the variable approaches a certain value. This indicates the function grows infinitely large or small near that point.

A limit involving a function and another function, where one function approaches infinity and the other approaches zero. The result depends on how quickly each function changes near the limiting point.

Finding the maximum area of a rectangle inscribed within a given region. This involves optimizing the area of the rectangle by finding the dimensions that yield the largest possible value within the constraints of the region.

The process of finding the limit of a function as x approaches a specific value. This involves analyzing how the function behaves as x gets arbitrarily close to the target value, but not necessarily equal to it.

Evaluating the definite integral for a given function over specified limits of integration. The process involves finding the antiderivative of the function and then evaluating it at the upper and lower limits, subtracting the results.

The value of the definite integral is equal to the area of the region bounded by the curve of the function, the x-axis, and the vertical lines representing the limits of integration.

The Mean Value Theorem states that for a differentiable function f(x) on a closed interval [a, b], there exists a point c in the open interval (a, b) such that the slope of the tangent line at c is equal to the slope of the secant line connecting the endpoints of the interval.

If the derivative of a function is positive on an interval, the function is increasing on that interval. If the derivative is negative, the function is decreasing.

If the second derivative of a function is positive, the function is concave up. If the second derivative is negative, the function is concave down.

A function can have a local minimum at a point if the derivative changes sign from negative to positive at that point. This is called the first derivative test for local extrema.

A function can have a local maximum at a point if the derivative changes sign from positive to negative at that point.

The process of finding the derivative of a function. This involves applying rules and techniques specific to different types of functions.

The derivative is a specific type of limit that calculates the instantaneous rate of change of a function at a particular point.
