Question

f(X)=4x-1 g(X)=x²+2 Find gof(X)?​

Answer 1

Hi friend here is your answer.

######################

f(x)=4x-1 and g(x)=x^2+2

So, gof(x)

= g{f(x)}

=g(4x-1)

So, g(4x-1)= (4x-1)^2 +2

= 16x^2 -8x+1+2

= 16x^2 -8x+3 ans.

Answer 2

Answer:

Step-by-step explanation:

Given f(x) and g(x), please find (fog)(X) and (gof)(x) f(x) = 2x   g(x) = x+3    

Quick Answer

(fog)(x) = 2x + 6

(gof)(x) = 2x + 3

                            &

f(x) = 2x

g(x) = x + 3

First let us find (fog)(x)

(fog)(x) = f(g(x)

            = f(x+3)

              = 2(x+3)

              = 2x + 6

==> (fog)(x) = 2x + 6

Now let us find (gof)(x):

(gof)(x) = g(f(x)

           = g(2x)

          = 2x + 3

==> (gof)(x) = 2x + 3
