Answer:
D. Range: y ≥ -3.
Step-by-step explanation:
(x - 4)^2 - 3
= x^2 - 4x - 4x + 16 - 3
= x^2 - 8x - 13
Since this is a parabola, there are no limits to the x-values, but there is a limit on the y-values: the y-values cannot exceed the highest or lowest point of the parabola, the vertex.
To find the vertex...
-b / 2a
8 / 2 = 4
(4 - 4)^2 - 3
= 0 - 3
= -3
So, your answer is D. Range: y ≥ -3.
Hope this helps!
