## Calculus with Applications (10th Edition)

Domain = $(-\infty,\infty)$ Range: $(-\infty,12]$
The arrows on either side of the curve indicate that x can take any value. Domain = $(-\infty,\infty)$ The function values peak at y=12 (included), For the values that are less, they are not bounded in the negative side... Range: $(-\infty,12]$
