Answer:

y = (7/8)x

Step-by-step explanation:

Exponential decay is represented when the number used is less than 1. 7/8 is the only choice that is less than 1.

y = (7/8)ˣ is an exponential decay because b = 7/8 < 1.

Exponential function

An exponential decay is in the form:

y = abˣ

where y, x are variables, a is the initial value of y and b is the multiplier which is less than 1.

From the question y = (7/8)ˣ is an exponential decay because b = 7/8 < 1.
