Question

Math problem

Answer 1

@jim_thompson5910 It's A right?

Answer 2

how did you get to A?

Answer 3

I plotted it using Mathway

Answer 4

if you were to plug x = 5 into the first piece, what would you get?

Answer 5

17?

Answer 6

so (5,17) is where the open hole is on the left piece

it's an open hole because of the \(\Large <\) sign (there is no line under the inequality sign)

Answer 7

plug x = 5 into the second piece and you get ???

Answer 8

-17

Answer 9

yes, which means (5,-17) is the location of that closed circle at the endpoint of the right half piece

Answer 10

So it would be B?

Answer 11

yes because A looks like the open circle is below y = 5, so there's no way it can be at (5,17)

Answer 12

Ok, thanks.

Answer 13

no problem
