We have been given graph of function . We are asked to find the value of
from the graph of
.
We know that to find an inverse function is a function that reverses another function. A function f(x) gives an output of y, when we input some value of x. The inverse of f(x) will give the same value of x from value of y.
So to find inverse of a function we need to switch all x and y values.
We can see that , so to to find value of
, we have to switch x and y values.
After switching x and y values, we will get:
Therefore, .
