Study Notes

Mathematical Constant e

  • e is a mathematical constant, approximately equal to 2.71828.

Exponential Function Characteristics

  • In the function f(x) = ab^cx, the variable a affects the y-intercept.
  • In the same function, changing c modifies the base from b to b^c.

Graph Functions

  • Functions can be represented graphically; label accordingly:
    • For f(x) = e^(2x) and g(x) = e^(3x), specific graphs must be assigned based on their growth rates.
    • Similarly, for f(x) = 3e^x and g(x) = e^x, appropriate graph labels should reflect the exponential growth differences.
    • For f(x) = e^x and g(x) = -3e^x, consider the impact of negative values on the graph appearance.

Ellipse Equation

  • The center of the ellipse represented by its equation is located at (-2, 5).

Polynomial Quotient

  • The quotient resulting from the expression 3x - 8 + 14/(x + 1) requires simplification and understanding of polynomial division principles.
