Question

Give the domain and range for the function. ( < Or > for your answer, but know that it should be ≤ or ≥)

Answer 1

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).
