Step-by-step explanation:

I'm going to assume you meant to write \sqrt{r+1} in the equation as +1 - 1 wouldn't make much sense since they would just cancel out.

a. f(-1) = \sqrt{-1 + 1} - 1\\ f(-1) = \sqrt{0}  - 1\\f(-1) = 0-1\\f(-1) = -1

b. f(24) = \sqrt{24 + 1} - 1\\ f(24) = \sqrt{25} - 1\\f(24) = 5 - 1\\f(24) = 4

c. f(x-1) = \sqrt{(x-1)+1} -1\\f(x-1) = \sqrt{x} - 1
