Short Answer: False The domain is the x value. It is the power in the equation. You can have almost any value for x depending on what you've been told about infinity. My definition for the domain (for this question) is - ∞ ≤ x ≤ ∞ for all real values. The graph is almost the same one as the last one I sent you, but it is slightly different.
Answer << False
PS How do you get such clear pictures? It's a joy to read.
Because the equation does not have any variable other than the x for the exponent. The domain would be all real numbers even ones less than 1/2 so the answer is False
