The functions f and g are defined by f: x = 4 - x and g: x = hx² + k. If the composite function gf is given by gf: x + 2x² - 16x
kozerog [31]

Answer:

Step-by-step explanation:

f(x) = 4-x

g(x) = hx^{2}+k

g(f(x)) = 2x^{2}-16x+26

so put  f(x)  in g(x)

h(4-x)^{2}+k

h((4-x)(4-x) + k

h(x^{2}-8x+16)+k

if h = 2 , then

2x^{2}-16x+32 + k

and we want 26  instead of 32 so subtract 6 so K = (-6)

2x^{2}-16x+32 + (-6)

2x^{2}-16x+32 - 6

2x^{2}-16x+26

h=2

k=(-6)
