C. Nonlinear

General Formulas and Concepts:

Algebra I

Step-by-step explanation:

Step 1: Define

y = 6x³ - 13

Step 2: Identify

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

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
