Find the derivative of fog(x) is f(x)= 2x-3 and g(x) = x^2-2

Given f(x)= 2x-3


g(x) = x^2
-2


We need to find
fog'(x)


First we need to determine the function
fog(x).


==> fog(x)= f(g(x) = 2g(x)
-3


                            = 2(x^2-3)
-3


==> fog(x) = 2x^2 -6 -3 = 2x^2
-9


==> fog(x)= 2x^2
-9


Now we will
differentiate.


==> fog'(x)=
4x


Then the derivative of fog(x) is fog'(x)=
4x
