If f(x) = -4x2 - 6x- 1 and g(x) = -x2 - 5x + 3, find (f+ g)(x).
o a. (f+ g)(x) = 5x2 + 11x+ 4
o b. (f+ g)(x) = - 5x2 - 11x + 2
o c. (f+g)(x) = -5x2 - x-4
o d. (f+9)(x) = 3x2 + x+4

Step-by-step explanation:

f(x) = -4x^2 - 6x - 1   g(x) = -x^2 - 5x + 3

find (f + g)(x)

-4x^2 - 6x - 1 + (-x^2 - 5x + 3) =

-4x^2 - 6x - 1 - x^2 - 5x + 3 =

-5x^2 - 11x + 2 <

395.84

step-by-step explanation:

2πrh+2πr²

2 (pie)(radius)(height)+2(pie)(radius)^2

its 4 because 2 times 2 is 4, if you double the number two you get four
