Question

find (fog) (2) for f(x)= -7x+3 and g(x) =x^2+4

Answer 1

f(x)=??? the entry is wrong. @Arizona1

Answer 2

f o g(x) Is a composition of functions I think you mistyped your f(x)
Because f(x) has no x dependance, f will always be -4, and so f o g will always be -4

Answer 3

my keys still shows no to both answers, please help :(

Answer 4

sorry I'm an idiot wrote it wrong sorry

Answer 5

(fog) (2) for f(x)= -7x+3 and g(x) =x^2+4
F comp g of x = -7[x^2+4]+3 = -7x^2-28+3=-7x^2-25

Answer 6

@Arizona1

Answer 7

(fog) (x)=f(g(x))=f(x^2+4)=-7(x^2+4)+3
put x=2 and we have -7(4+4)+3=-56+3=-53
