Question

What is the range of the function g(x) = |x – 12| – 2?

Answer 1

B

Y is greater than or equal to -2

Answer 2

[-2 , +∞[

Explanation:

g(12) = |12 - 12| - 2 = -2

if x ≠ 12 then |x - 12| ≥ 0 because the absolute value I should always positive.

then |x – 12| – 2 ≥ -2

then g(x) ≥ -2

then the range is [-2 , +∞[
