Answer:
see below
Step-by-step explanation:
An exponential term with a base greater than 1 will increase at an increasing rate. If the base is less than 1 (a fraction), then it will decrease at a decreasing rate.
Any (non-zero) base to the 0 power will have a value of 1, so the function will have a y-intercept at (0, 1) if there is no multiplier (vertical scale factor) of the exponential factor. The y-intercept will be the value of the multiplier.
