Question

What is the range of the function defined as y=5

Answer 1

$\bf \begin{array}{cllll} x&y\\ \textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\ -7&5^{-7}\to \frac{1}{5^7}\to \frac{1}{78125}\\\\ -3&5^{-3}\to \frac{1}{5^3}\to \frac{1}{125}\\\\ 0&5^0\to 1\\\\ 3&5^3\to 125\\\\ 7&5^7\to 78125 \end{array}$

so... you can keep on going towards the negatives with "x", or towards the positives with "x", notice, if the "x" is negative, "y" is just a fraction, positive, but a fraction

and if "x" is positive, "y" is a positive integer
even when x =0, "y" never became 0, and is never negative either

so, the range is, "y" is always positive, but not 0, or  y>0
