• Linear

• Quadratic

• Exponential

• None of them

Answer explanation

You can graph it in Demos to see that it does not look linear (a straight line), quadratic (u-shaped) or exponential (like 1 hockey stick).

• Linear

• Quadratic

• Exponential

• None of them

Answer explanation

Whenever there is a variable in the exponent, it is exponential.

You can graph it in Demos to see that it is exponential (shaped like a hockey stick).
