Question

Consider the functions f and g where f(x) = − 3x - 5 and g x( ) = x - 2 . Find the inverse function, f ^−1.

Answer 1

Inorder to find the inverse of any fuction

Suppose f(x)= x and x=y

X=-3y-5

Now try making y the subject of the equation.

(X+5)÷(-3) =y

Now

Y is the inverse of function of f(x)
