1.Given the function f(x) = -2c + cx - x^2? and f^-1(5) = -1, find c

Here we have a quadratic function and we want to find the value of a constant with a given restriction.

We will find that c = 8.

So we have the function:

We know that:

Notice that the above equation means that:

Then we just need to solve the above equation for c:

So we found that the value of c is 8.

This means that the function is:

You can see the graph below:
