Answer:

$solve \: when \: (f + g) \:(4) \\ \\ first \: solve \: for \: f(x) \\ \: \\ solution \: .... \\ \\ f(x) = 4x - 3 \\ f(4) = 4(4) - 3 \\ f(4) = 16 - 3 \\ f(4) = 13 \\ \\ \\ now \: solve \: for \: g(x) \\ \: \\ solution \: .... \\ \\ g(x) = {x}^{3} + 2x \\ g(x) = {(4)}^{3} + 2(4) \\ g(x) = 64 + 8 \\ g(x) = 72 \\ \\ (f) - (g) = 13 - 72 \\ (f) -(g) = -59$

What is the line of symmetry of the parabola y=x2+6x-9?

Rzqust [24]

First we have to find the vertex (h,k) h is also x and it also is the a xis symmetry

1st: group the number
(X2+6x)-9

2nd: use b/2

6/2 = 3 , 3^2= 9

(X2+6x+9)-9-9

(X2 + 3)-18

Vertex is 3,-18 so the symmetry is 3
