A(n) _________________ function will MULTIPLY the same number each time.

• Linear

• Quadratic

• Exponential

• All of the above

• Linear 

• Exponential 

• Neither 

In the first year of an annual 5K run there were 120 participants. In the 2nd and 3rd year of the 5K run, there were 180 and 270 participants respectively. This situation is best modeled by a(n) ________________ function.

• linear

• quadratic

• exponential

• none of the above

Is the equation linear or exponential?

• Linear

• Exponential

What is the difference between a quadratic function and an exponential function in terms of reaching 0?

• An exponential function can never equal 0, while a quadratic function can equal 0.

• Both quadratic and exponential functions can never equal 0.

• Both quadratic and exponential functions can equal 0.

• A quadratic function can never equal 0, while an exponential function can equal 0.

As x increases beyond 25, which function will have the largest value?

• f(x) = 1.5^x

• g(x) = 1.5x + 3

• h(x) = 1.5x²
