Explanation:
Parabola in picture, we can look that, domain is R.
And this range is ≥ 2.
How that this is answer?
- Domain is ilustrated by x-axis. We get fact, in parabola, for interval (-∞ , ∞) is defined. Other notations from interval, is the set R (Real Numbers)
- Parabola in picture above, we get fact, this graph as positive definite (above x-axis). Consider that range ≥ 2 (2 is minimum value from graph).
