Answer:
g(f(x) = 12x^2-2
Explanation:
solution:
given,
f(x)=3x^2-1
g(x)=4x+2
g(f(x)=?
here,
g(f(x) = g(3x^2-1) [put the value of f(x) given]
=4(3x^2-1)+2 [ now put the value of g(x) and in the place of x put 3x^2-1]
=12x^2-4+2 [ by multiplying 4(3x^2-1) ]
= 12x^2-2 ans..
So g(f(x)=12x^2-2
hope its helps , I tried my best to explain there
hope you understand it as i am terrible at explaining like this ...
have a good time(•‿•)
