Question

?? math-domain and range

Answer 1

Domain: All real numbers (infinite) Range:
`y \leq -4`

Explanation:

For the domain, the x-axis will continue to be used for the parabola, because the parabola can go on forever and can use an x- value on the x-axis. For the range, the largest number the parabola will go up to is -4. Therefore, if that is the highest point/ where the vertex is, the highest point on the y-axis is -4, resulting in the answer y can be equal to or less than -4 (y
`\leq` -4), since the parabola will continue to go down with the reflection over the x-axis.
