Question

Does each equation represent exponential decay or exponential growth?

Answer 1

Answer:

  decay: a, b

  growth: c, d, e, f

  neither: g

Step-by-step explanation:

A function is exponential if it has the independent variable in an exponent. g(x) is a linear function, not an exponential function.

__

An exponential function is a growth function if the coefficient of the variable is positive and the base of the exponent is greater than 1. It is a decay function if the exponent is positive and the base is less than 1.

The first two functions are decay functions. The remaining four exponential functions are growth functions.
