Question

Determine which is the graph of the function.
f(x) = {3x + 2 if < 5; -3x - 2 if x ≥ 5

Answer 1

Do you know how to graph y=3x+2?

Answer 2

My teacher allows us to use graphing calcs so yes

Answer 3

ok well I would draw y=3x+2 on a paper
and erase the part of the line that comes after x=5 and put a hole at x=5
since it is says f(x)=3x+2 when x<5 (which means this part does not include what happens at x=5)

Answer 4

then on that same paper (the same graph) draw y=-3x-2

Answer 5

but for it erase every part of that line that comes before x=5

Answer 6

Okay one sec. Lemme start that and see if i get it.

Answer 7

would it look something like this?

Answer 8

well you have some overlapping x values there
