Answer:
6, y = 2(x - 5), 0
Explanation:
a) To find f(2), substitute 2 for x: f(2) = 2/2 + 5 = 6
b) Let's find the inverse function of f(x). 1) replace f(x) with y: y = x/2 + 5
2) interchange x and y: x = y/2 + 5
3) Solve this result for y: y/2 = x - 5, or y = 2(x - 5) This is the inverse of f
(c) the inverse of f at x = 5 is y = 2(5 - 5) = 0
