Question

Graph the function. Then State the domain and range. Also increasing and decreasing​

Answer 1

First function: domain: [-9,\infty)[−9,∞) , range: (-\infty, -2](−∞,−2] , decreasing

Second function: domain: (-\infty, \infty)(−∞,∞) , range: (-\infty, \infty)(−∞,∞) , increasing

Third function: domain: [3, \infty)[3,∞) , range: [-5,\infty)[−5,∞) , increasing

Answer 2

See below, I will let graphing part to yourself.

Explanation:

First function: domain:
`[-9,\infty)`, range:
`(-\infty, -2]`, decreasing

Second function: domain:
`(-\infty, \infty)`, range:
`(-\infty, \infty)`, increasing

Third function: domain:
`[3, \infty)`, range:
`[-5,\infty)`, increasing
