Question

Jordana drew the function below. Which statement correctly explains whether or not her function is linear? On a coordinate plane, a parabola opens up.

Answer 1

D. It is not linear because it does not have a constant rate of change.

Explanation:

Given

See attachment for graph

Required

Linear or not? and why

Linear functions have constant slopes (i.e. constant rates of change)

The attached function is a curve, and curves do not have constant slope.

Hence, we can conclude that the function is not linear because it does not have a constant slope.
