Question

Help Please!!!

If f(x) = 2x – 1 and g(x) = – 2, find [g ◦ f](x).

Please show your work! Thanks

Answer 1

Answer: 4x²-4x-1

Step-by-step explanation:

(g · f)(x)=(2x-1)²-2=4x²-4x+1-2=4x²-4x-1

Answer 2

Answer:

$[g\circ f](x)=-2$

Step-by-step explanation:

$[g\circ f](x)\quad \textnormal{means "put f inside g}$

$\therefore [g\circ f](x)=-2$

since g doesnt contain x (g is a constant function)
