Question

Which equations represent exponential functions? Select all that apply.

Question 1 options:


f(x)=3x2



f(x)=4x



f(x)=7*3x



f(x)=6x−1

Answer 1

`{4}^(x)`

`7 * {3}^(x)`

Explanation:

A exponential equation is represented by

`y = ab {}^(x)`

where a is the initial value, and b is the constant factor.

• 3x^2 is wrong becuase that represent a quadratic
• 6x-1 is wrong becuase that represent a linear equation

The answer 4^x and 7×3^x are right
