Question

[−16,9]∪(9,∞)
I need help immediately please

Answer 1

`[\sf{-16,\infty})`

Step-by-step explanation:

`\textsf{Here,}\\\sf{[-16,9]}\textsf{\ contains all the numbers from -16 up to 9 inclusive (including 9).}\\\textsf{The set (9,}\infty)\textsf{ contains all numbers greater than 9. That means the union of the}\\\textsf{two sets will be all numbers from -16 to }\infty.`

`\textsf{Here are set builder notations of both intervals:}`

`[-16,9]=\{\textsf{x:}-16\le x\le 9\}}\\(-9,\infty)=\{\textsf{x: x} > 9\}`
