Answer: 6
Step-by-step explanation:
To find the inverse of a function, we need to switch the roles of x and y in the equation and solve for y. In this case, we have f(3) = 6, which means that when x is 3, f(x) is 6.
To find f^-1(6), we need to switch the roles of x and y and solve for x. Let's do that:
1. Start with the equation f(x) = 6.
2. Switch the roles of x and y to get x = 6.
3. Solve for x. In this case, x is already isolated, so we have x = 6.
Therefore, f^-1(6) = 6.
So, if f(3) = 6, then f^-1(6) is also equal to 6.
