Question

PLS HELP!!!!!!!!!!!!!!!!!!!!!!

Answer 1

Option B: -∞ < y ≤ 0

Explanation:

The correct answer is **Option B: -∞ < y ≤ 0**. This is because the highest point of the quadratic function is on the x-axis, which means the range of the function must be less than or equal to 0. Therefore, all possible y-values are less than or equal to 0.

Answer 2

`-\infty < y\le0`

Explanation:

The y-values (range/output/graph) cover the portion
`(-\infty,0]`

The interval is always open on
`-\infty` and
`\infty` because their values are unknown => It is impossible to reach
`-\infty` and
`\infty`
