Questions and Answers

Explain how you might use the properties of logarithms to simplify a complex equation before solving it. Provide an example of such an equation.

Logarithmic properties allow combining or separating logarithmic terms. For example, the equation log(x^2) + log(y) = log(z) can be simplified to log(x^2 * y) = log(z), then x^2 * y = z, making it easier to solve for one of the variables.

Describe a scenario where understanding the domain of a logarithmic function is crucial in a real-world application. Give a specific example.

In sound intensity calculations, the domain is crucial because you can't have a negative or zero intensity. For decibel calculations using the formula dB = 10 * log10(I/I0), where I is the sound intensity and I0 is the reference intensity, I must be greater than zero for the logarithm to be defined.

How does changing the base of a logarithm affect the graph of the function? Explain using the change of base formula.

Changing the base of a logarithm scales the function vertically. According to the change of base rule: log_a(x) = log_b(x) / log_b(a). Thus, if a is changed, we are in effect multiplying the log function by a constant reciprocal to log_b(a), resulting in a vertical stretch or compression.

Explain how the graph of $y = log_2(x)$ is transformed to obtain the graph of $y = log_2(x-3) + 1$.

<p>The graph of $y = log_2(x)$ is shifted 3 units to the right and 1 unit upwards to obtain the graph of $y = log_2(x-3) + 1$.</p> Signup and view all the answers

Describe how you would solve an exponential equation where the bases cannot be easily made the same. Provide an example.

<p>Take the logarithm of both sides of the equation. For example, to solve $3^x = 7$, take the logarithm of both sides: $log(3^x) = log(7)$, which simplifies to $x * log(3) = log(7)$. The solution is then $x = log(7) / log(3)$.</p> Signup and view all the answers

What is the significance of the natural logarithm (ln) in calculus, and why is it often preferred over other bases?

<p>The derivative of <code>ln(x)</code> is <code>1/x</code>, which is simpler than the derivative of <code>log_a(x)</code>. This simplicity makes it easier to work with in integration and differentiation.</p> Signup and view all the answers

How does the asymptote of a logarithmic function relate to the domain of that function?

<p>The asymptote of a logarithmic function represents the boundary of its domain. Since logarithmic functions are only defined for positive arguments, the vertical asymptote occurs where the argument approaches zero, and the function is undefined.</p> Signup and view all the answers

Explain the difference between logarithmic and exponential growth and provide an example of each in real-world phenomena.

<p>Exponential growth increases rapidly, such as compound interest on an investment. Logarithmic growth increases more slowly over time, with growth decreasing as the input increases, such as the perceived loudness of sound relative to its intensity.</p> Signup and view all the answers

If you are given $log_b(M) = x$ and $log_b(N) = y$, express $log_b(M^2 / N)$ in terms of $x$ and $y$. Show your work.

<p>$log_b(M^2 / N) = log_b(M^2) - log_b(N) = 2 * log_b(M) - log_b(N) = 2x - y$.</p> Signup and view all the answers

Describe a situation where you would need to use both exponential and logarithmic functions to solve a single problem. Provide a brief example.

<p>Determining the time it takes for an investment to reach a certain value with continuous compounding requires both types of functions. For example, to find how long it takes for an investment of $1000 to double at a 5% continuous interest rate: $2000 = 1000e^{0.05t}$, solve for $t$ using logarithms: $t = ln(2) / 0.05$.</p> Signup and view all the answers
