Question

Johnny thinks that the domain of this graph is (-6.25, + ∞) and the range is (-∞, ∞) is he correct? If not, please write the correct answer.

Answer 1

This means that Johnny exchanged the values, so he is mistaken. The domain is (-∞, ∞) and the range is (-6.25, + ∞).

Explanation:

Domain: Values that the input x assume.

Range: Values that the output y assume.

In this question:

x values are in the interval of (-∞, ∞).

y values are in the interval of (-6.25, + ∞).

This means that Johnny exchanged the values, so he is mistaken. The domain is (-∞, ∞) and the range is (-6.25, + ∞).
