Which of the following is an exponential function?

a.

y = 3x
b.

y = 2x − 4
c.

y = x3

d.

y = 3+5x

Step-by-step explanation:

A:  y = 3x is a linear function;

B:  y = 2x - 4 is also a linear function;

C:  y = x^3 (not x3) is a power function;

D:  y = 3 + 5x is a linear function

An exponential function looks like y = a(b)^c; none of these possible answers fit!  Ensure that you have copied this problem down completely and correctly.

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
