Question

Heeeeelllllppppppppppp!

Find the domain of the following function.

A. all real numbers
B. all real numbers except for 2
C. - ∞ < x ≤ 10
D. - 4 ≤ x ≤ 10

Answer 1

That's a piecewise defined function and based on its definition we got the answer D.
(By combining -4≤x<2 and 2≤x≤10)
D. - 4 ≤ x ≤ 10

Answer 2

The answer is - 4 ≤ x ≤ 10 since those are linear pieces so all that needs to be done is the union of the intervals for the piecemeal function
