Question

Without graphing, determine whether the function represents exponential growth or exponential decay. Then find the y-intercept.


A. Exponential growth; 4
B. Exponential decay; 4
C. Exponential growth; 0
D. Exponential decay; 5

I will give brainliest to the correct answer!

Answer 1

Answer:

Exponential decay; 4

Step-by-step explanation:

This represents exponential decay, because the number which is being raised to the power x is less than one. This means that as x increases, y decreases.

The y-intercept occurs when x is equal to zero. When x = 0, we have $y = 4(5/6)^0 = 4(1) = 4$, so the y-intercept is 4.
