Use the function to answer the question.

f(x)=x^2-4; g(x)=x+2

which is equal to (f+g)(x)?

x^2-2

x^2+4x

x^2+x-2

x^3+2x^2-4x-8

x^2+x-2

Step-by-step explanation:

f(x)=x^2-4;

g(x)=x+2

(f+g)(x) = x^2-4+ x+2

Combine like terms

           =x^2 +x -2

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

the answer is c.
