-3, 1 is the answer because the spot is on the -3 and in the first low with the Y-axis and stuff .
Answer:
no
Step-by-step explanation:
coordinates pair (2,11) does not go with the inequality
When taking square roots, you can't take square roots of negative roots of negative numbers. So, what will work for the domain of u(x) is what makes u(x) zero or more. We can make an inequality for that.
u(x) ≥ 0.

9x + 27 ≥ 0 by squaring both sides
9x ≥ -27
x ≥ -3
So the domain of the function is when x ≥ -3 is true.
combine your like terms and get x by its self
