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

Answer:

Step-by-step explanation:

3x – 4(x - 4) + 4 = 13

=> 3x - 4x + 16 + 4 = 13

=> - x + 20 = 13

=> - x = 13 - 20

=> - x = - 7

=> x = 7
