Answer: f^-1(1) + f(-14) = 20, f^-1(-2) = 10

Explanation:

When finding the inverse through a table of functions, we are doing the opposite of a function. For example:

If f(9) = 1, then, let me ask you, what is f^-1(1)? Well, that's just 9! You're basically doing the opposite.

An inverse through a table of functions is basically you trying to figure out what x-value did you input to get the f(x) value. A regular function is you trying to figure out what f(x) value did you get by inputting an x-value.

So, the inverse of f(1) is 9, and the regular function of -14 is equal to 11. We then add. 11+9 = 20.

The inverse of -2, like I said before, is you trying to find out the x value you put to get -2. Well looking at the table, it seems x was 10. Thus the inverse of -2 is 10.
