Question

if f(x)=1/1-x and g(x) = x then fog(x) =

Answer 1

GIVEN :

The functions f is defined by and g is defined by

TO FIND :

The value of the composite function

SOLUTION :

The composite function of f and g is defined by

Since

Since put the value of x is in the function f(x)

Using the distributive property :

a(x+y)=ax+ay

Adding the like terms

∴

Therefore the value of the composite function of f and g is x

∴   is x.
