For f(x)=4x+2 and g(x)=x^2-6, find (f+g)(x)

a) 4x^3-4
b) 4x^2-16
c) x^2+4x-4
d) x^2+4x+8

The answer would be x^2+4x-4

Step-by-step explanation:

You can solve this by plugging 4x+2 into (f+g). 4x+2 would equal f. x^2-6 would equal g. plugging them in gets you 4x+2+x^2-6. If we simplify it we would end up with x^2+4x-4

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
