I think 70 because playing on a varsity, i think, means to play both sports. So I added 10 to the number of students that play basket ball, which is also equal to the number of students that like tennis.

The graph of the invertible function f is shown on the grid below <br> What is the value of f^-1(6)
dolphi86 [110]

Given:

The graph of an invertible function f<em> </em>is given.

To find:

The value of f^{-1}(-3).

Solution:

We know that, if the graph of an invertible function f passes through the point (a,b), then the inverse function f^{-1} passes through the point (b,a).

From the given graph it is clear that the graph of the function f passes through the points (-5,-3).

So, the inverse function f^{-1} must be passes through the point (-3,-5).

Therefore, the value of inverse function is -5 at x=-3. So, the value of f^{-1}(-3) is -5.
