Consider the function f(x)= 2/5x-4 a.) find the inverse of f(x) and name it g(x). show and explain your work. b). use composition to show that f(x) and g(x) are inverses of each other. c). draw the graphs of f(x) and g(x) on the same coordinate plane. explain what about your graph shows that the functions are inverses of each other.

a)

Step-by-step explanation:

Since we have given that

a.) Find the inverse of f(x) and name it g(x).

Let f(x) = y

So, it becomes

Switching x to y , we get

b) . Use composition to show that f(x) and g(x) are inverses of each other.

Similarly,

so, both are inverses of each other.

c) Draw the graphs of f(x) and g(x) on the same coordinate plane.

As shown below in the graph , Since for inverse function we need an axis of symmetry i.e. y=x

And both f(x) and g(x) are symmetry to y=x.

∴ f(x) and g(x) are inverses of each other.
