Question

Match the description with the correct symbolic expression.
-a function that is not linear 
A) $f ( x ) = 7 x + 2$
B) $f ( x ) = - 4$
C) $f ( x ) = - 6 x + 7$
D) $f ( x ) = x ^ { 2 } - 6$

Quizplus · Accepted Answer

A function that is not linear does not have a constant rate of change and can include exponents, as seen in choice D with $x^2$, which makes it a quadratic function, not a linear one. Choices A, B, and C are all linear functions.

Match the Description with the Correct Symbolic Expression f(x)=7x+2f ( x ) = 7 x + 2f(x)=7x+2
