Question

How do you identify equations as exponential growth, exponential decay, linear growth or linear decay `f(x) = 4 (3/2)^x`?

Answer 1

Growth is an increasing function, decay is a decreasing one.
Exponential means that the function contains and exponent, and linear means that a graph of the equation is a straight line.

Explanation:

For the expression given we have an exponent, so the result will be exponential. Because the exponent is applied to a positive value (`3/2`) it will be a growth function, increasing as "x" increases.
