Question

f (x) =x2 , g(x) = 3x + 2 (i) (f+g) (x)​

Answer 1

Answer:

please mark me as brainlest please

Step-by-step explanation:

f(x)=3x−2

(g.f)

−1

=x−2

Let y=x−2⇒x=2+y⇒y

−1

=2+x

((g.f)

−1

)

−1

=2+x

⇒g.f=2+x

⇒g(f(x))=x+2

⇒g(3x−2)=3x−2+2=3x

Let 3x−2=t⇒x=

3

t+2

g(t)=

3

t+2

+2

g(t)=

3

t+8

∴g(x)=

3

x+8
