How do you go about graphing piecewise functions?

Answer 1

so each one tells you where to plot the points, its like graphing a regular graph, so when x<0 you will graph -x-3

Answer 2

that would be the top one

Answer 3

would be the second one

Answer 4

for x < 0 you use -x-3, that is between \((-\infty, 0)\)
for x =0 you use 5, that is at 0
for x > 0 you use \( x^2\) that is between \((0, +\infty)\)

Answer 5

and that would be the third one, together they form the piece wise function's graph

Answer 6

That makes sense, thank you so much!

Answer 7

youre welcome, do you get how i got to the graph that i did?

Answer 8

Yes, I just wasn't sure how to show that x was greater, less than, or equal to 0 on a graph, but what you drew seems pretty straight forward.

Answer 9

ok, good(:
