Let f (x) = 11x + 2x2 and g(x) = -7x - 3x2 + 4. Find (f +9) (x) and (f -g)(x). Then evaluate f + g and f - g for = 2.

answer: it is d

step-by-step explanation:

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system

hello! just here for points! though i wish i knew!
