Question

Which of the following best describes the equation below?

y = 6x3 - 13
A.
linear
B.
neither linear nor nonlinear
C.
nonlinear
D.
both linear and nonlinear

Answer 1

C. Nonlinear

General Formulas and Concepts:

Algebra I

• Linear - Proportional relationship y = mx + b
• Nonlinear - Any graph that has a degree x higher than 1

Explanation:

Step 1: Define

y = 6x³ - 13

Step 2: Identify

We see a cubic function. Quadratics, Cubics, Quartics, etc. are all nonlinear equations.
