Question

Given f(x) = 3x + 2 and g(x) = 2x - 1, find (g(x))2.

Answer 1

Answer:

C (if the sign after the digit 1,2,3,4 is not minus !!!)

Step-by-step explanation:

$f(x)=3x+2\\\\g(x)=2x-1\\\\\\g^2(x)=(gog)(x)=g(g(x)=g(2x-1)=2(2x-1)-1=4x-2-1=4x-3\\\\\\if \ you\ means \ g(x)*g(x)\ then\\\\(g(x))^2=(2x-1)^2=4x^2-4x+1:\ answer \ C$
