One exterior angle of a regular pentagon measures 60° 72° 90° 120°

Step-by-step explanation:

The y-intercept is where the function crosses the y-axis (when x=0).  The y-intercept of f(x) is 3, and the y-intercept of g(x) is also 3.

g(x) increases as x increases, so it is an increasing function.  f(x) decreases as x increases, so it is a decreasing function.

The average rate of change on the interval [0, 1] of f(x) is:

(f(1) - f(0)) / (1 - 0)

(1 - 3) / 1

-2

The average rate of change on the interval [0, 1] of g(x) is:

(f(1) - f(0)) / (1 - 0)

(4 - 3) / 1
