Question

For the x-values 1, 2, 3, and do on, the y-values of a function form a geometric sequence that decreases in value. What type of function is it?

A. Exponential decay

B. Exponential growth

C. Increasing linear

D. Decreasing linear

Answer 1

A. Exponential decay

Explanation:

Since the function decreases in value, it represents a decay, or a decrease.

Also, the function forms a geometric sequence, that is, the product between consecutive values is the same, which is the mark of an exponential function. So the correct option is option A.
