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