If f(x) = 3x2 + 6x + 12 and g(x) = x2 – 6x + 3, what is f(x) + g(x)?

a. 2x^2 - 12x - 15

b. 4x^2 + 12x + 15

c. 4x^2 + 15

d. 2x^2 + 12x + 15

I think it would be C. 4x^2 +15 since positive 6 and negative 6 cancel each other out and you just combine like terms.

a) false; the points do not have to be in a straight line.

step-by-step explanation:

the points could be in the shape of a triangle

b is incorrect

c is incorrect because it is saying the immediately don't form one when they are capable of doing so

d is incorrect

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )
