Answer:

g(f(x) = 12x^2-2

Step-by-step 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(•‿•)
