The rate of change of two functions are being compared. One function, f(x) is represented by the equation f(x) = -5x – 1, while the other function, g(x) is represented in the table. Which is true? The rate of change for f(x) is less than the rate of change for g(x)., The rate of change for g(x) is less than the rate of change for f(x)., The rate of change for f(x) and g(x) are equal., The rates of change cannot be compared because f(x) is a linear function and g(x) is an exponential function.

Back

The rate of change for f(x) is less than the rate of change for g(x).
