Question

question: determine whether the function is one-to-one. If it is sketch the graph of its inverse.i already found out it is a one-to-one, i just don't know how to graph its inverse

Answer 1

The inverse function of f(x) = y is f(y) = x

This means, switch the coordinates of the points of the graph

If we choose a point on the given graph like (5, 3) it will be (3, 5) in the inverse function

Also, point (-5, -3) it will be (-3, -5) in the inverse function

You can plot them with point (0, 0) and draw the curve

Let me try to show it

It will be like that
