Answer:
See below in bold.
Step-by-step explanation:
The graph is Β a parabola (shaped like the letter U ) and the lowest point is at the origin (0,0).
Now x can be any value so its domain is All real values of x.
There are no real values for f(x) Β below 0, Β (as the minimum is at (0,0), Β so it's range is All real values of f(x) β₯ 0.
