Question

Which of the following is true about a nonlinear function?


A: It has a constant rate of change.

B: It can be curved.

C: It looks like a straight line.

D: It must cross the origin.

Answer 1

Hello and Good Morning/Afternoon:

Let's take this problem step-by-step:

What is a linear function:

  ⇒ function that graphs in a straight line

Therefore whatever doesn't meet the linear function's definition:

  ⇒ isn't linear, therefore it is nonlinear

Let's consider all the choices of what fits a nonlinear's function definition:

• A. It has a constant rate of change

      ⇒ it is false because only a linear line has a constant rate of change

• B. It can be curved

     ⇒ it is true because nonlinear lines are not straight, thus they can be

        curved

• C. It looks like a straight line

     ⇒ it is false because nonlinear lines are the opposite of linear lines

          which are straight

• D. It must cross the origin

    ⇒ it is false as there are no such requirements for either

        linear/nonlinear lines

Answer: (B)

Hope that helps!
