Explanation
to graph a function and its inverse, all you have to do is graph the function and then switch all x and y values in each point to graph the inverse, so
Step 1
draw the line y=x
Step 2
switch all x and y values in each point, in the graph it will look like if the line y=x( green) is a mirror.
[tex](x,y)\rightarrow(y,x)[/tex]
[tex]\begin{gathered} A(7,8)\rightarrow(8,7) \\ B(3,7)\rightarrow(7,3) \\ C(-3,2)\rightarrow(2,-3) \\ D(-4,-2)\rightarrow(-2,-4) \end{gathered}[/tex]
I hope this helps you
