When a function is equal to a single number, such as y = 5, y = -2, y = 8, what does the graph look like?
anonymous
  • anonymous
horizontal lines
anonymous
  • anonymous
The 5, -3/2, and 1/2 are the y-values. The stuff after if gives the corresponding range of x-values so y = 5 from where x is close to -3 to close to -2. Because it's < and not ≤, use open circles at the ends of your horizontal lines.|dw:1439341137358:dw|

okay
anonymous
  • anonymous
now draw y = -3/2 from where x = -2 to approximately x = 3
anonymous
  • anonymous
what would that look like?
anonymous
  • anonymous
that's also a horizontal line. starting at the point (-2, -3/2) and ending at (3, -3/2). For the ends, use a closed circle for ≤ and an open circle for <
anonymous
  • anonymous
can you draw it?

the horizontal line y = -3/2 from x = -2 to 3 with a closed circle at -2 and open circle at 3.
anonymous
  • anonymous
can you draw the third one?
anonymous
  • anonymous
I'll try

roughly
anonymous
  • anonymous
you're right on the closed circles and the y-value, but it goes from 3 to 4 so it shouldn't overlap the second line.|dw:1439342176965:dw|

that was an accident
