Question

Which of the following is an exponential function y=x^1/2 y=2x^3 y=3^x

Answer 1

(c) y = 3^x

Explanation:

A function is described as exponential if the independent variable is found in the exponent.

Choices

y = x^(1/2) . . . a square root function, not exponential

y = 2x^3 . . . . a cubic (polynomial) function, not exponential

y = 3^x . . . . . an exponential function
