If f(x)=2x-6 and g(x)=x^3 what is (g f)(0)

marin [14]

ANSWER

$(g \circ \: f)(0) = - 216$

EXPLANATION

The functions are:

$f(x) = 2x - 6$

$g(x) = {x}^{3}$

$(g \circ \: f)(x) =g(f(x))$

$(g \circ \: f)(x) =g(2x - 6)$

We substitute f(x) into g(x) to obtain:

$(g \circ \: f)(x) =(2x - 6)^{3}$

We now substitute x=0 to obtain;

$(g \circ \: f)(0) =(2(0) - 6)^{3}$

$(g \circ \: f)(0) =(- 6)^{3}$

This simplifies to:

$(g \circ \: f)(0) = - 216$

What is the value of x? Enter your answer in the box.

creativ13 [48]

(10x-20)= (6x+8) subtract 6 from each side
(4x-20)=(+8) add 20 to each side
(4x)=(28) divide both sides by 4
x= 7
