Answer:
Answer: C. y ≥ 0.
Step-by-step explanation:
Domain and Range
To find the range of a function given its graph we draw imaginary horizontal lines from -∞ to +∞. The values of y where the line meets the graph belong to the range.
The graph shows a parabola opening upward. If we draw horizontal imaginary lines, the first point where those lines meet the graph is at y=0. From there up, the lines and the graph meet at two points.
Thus the range of the function is [0,+∞) or written in interval form: y ≥ 0.
Answer: C. y ≥ 0.
