Question

Referring to the figure, write a compound inequality that describes
the graph shown. http://www.ppstest2.com/images2/AL6002.jpg

Answer 1

@BunnyBree @Jhannybean

Answer 2

When it's a closed circle, that means it's inclusive, meaning the point where the dots are, are included in the inequality.

Answer 3

so what do i do @Jhannybean

Answer 4

on one side, you have x ranging from 1 to - infinity. Then the point jumps from 1 to 5, and includes all the points starting at 5, all the way to + infinity

Answer 5

ok

Answer 6

ok um what are all those signs

Answer 7

meant to write \(x \le 1\) or \(x \ge 5\)

Answer 8

ok so what do i do with x<=1 or x>=5

Answer 9

The way I wrote it is in the notation of the x domain, that means that whatever x value you have extends from 1 which is included in the inequality, all the way to -ve infinity. Also, x includes 5 and extends to +ve infinity.

More specifically, your inequality would simply be \((x: x\le 1 \ or \ x\ge 5)\)

Answer 10

You're just asked to write a compound inequality that relates the two points, and there you have it :)

There is nothing more you have to do with it, really.
