Question

let f(x)=3x-4 and g(x)=-x^2. Evaluate the composite function. (gf)(0)
A.0
B.-16
C.16
D.-10

Answer 1

what is the resulting function if you have (g o f)(x) ?
Replace all 'x' in g(x) with the function defined in f(x)
So \[g(x) = x^2 => (f(x))^2 => ??\]

Answer 2

Thank you!

Answer 3

gof=g(f(x))
g(3x-4)=-(3X-4)^2
=-{3(0)-4}^2 putting x=0
=-(-4)^2
=-16

Answer 4

u r welcome
