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) = h $x^{2}$ +k

g(f(x)) = 2 $x^{2}$ -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

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

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

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

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

2 $x^{2}$ -16x+26

h=2

k=(-6)
