Incorrect Question 12 Find the inverse of the function. f(x) = \sqrt{x+5}, x \ge 5 r-1(x) = x2+5, x \ge 0 Not a one-to-one function r-1(x) = x2-5, x \ge 0 r-1(x) = x+5, x \ge 0 Incorrect Question 13 Find the inverse of the function. f(x) = (x-8)2, x \ge 8 Not a one-to-one function r-1(x) = \sqrt{x} + 8, x \ge 0 r-1(x) = \sqrt{x} - 8, x \ge 8 r-1(x) = -\sqrt{x} + 8, x \ge 0

          Incorrect
Question 12
Find the inverse of the function.
f(x) = \sqrt{x+5}, x \ge 5
r<sup>-1</sup>(x) = x<sup>2</sup>+5, x \ge 0
Not a one-to-one function
r<sup>-1</sup>(x) = x<sup>2</sup>-5, x \ge 0
r<sup>-1</sup>(x) = x+5, x \ge 0
Incorrect
Question 13
Find the inverse of the function.
f(x) = (x-8)<sup>2</sup>, x \ge 8
Not a one-to-one function
r<sup>-1</sup>(x) = \sqrt{x} + 8, x \ge 0
r<sup>-1</sup>(x) = \sqrt{x} - 8, x \ge 8
r<sup>-1</sup>(x) = -\sqrt{x} + 8, x \ge 0

Incorrect
Question 12
