If f(x) = x + 4 and g(x) = x^3, what is (gºf)(-3)?

(gºf)(-3)= ( x + 4 )^3

(gºf)(-3)= x^3 +12x^2 + 48x + 64

(gºf)(-3) =  (-3)^3 +12(-3)^2 + 48(-3) + 64

(gºf)(-3) = -127

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
