Question

If f (x) -3x + 2 and g (2) = x + 1 find g(f(x)) please helppp

Answer 1

$\left \{ {{f(x)=-3x+2} \atop {g(x)=x+1}} \right.$

To find g(f(x)), Substitute f(x) in g(x).

$g(-3x+2)$

Then substitute x = -3x+2 in g(x) = x+1

$g(-3x+2)=(-3x+2)+1\\g(-3x+2)=-3x+2+1\\g(-3x+2)=-3x+3$

Therefore, the answer is $g(f(x))=-3x+3$
