Exponential Word Problems Find the Decay or Growth

Given the function f(x) = 1.07^x, how do you know the exponential function shows growth or decay?

• Growth or decay is determined by the value of the base

• Growth or decay is determined by the value of the exponent

• Because exponential functions are always growth functions

• Because exponential functions are always decay functions
