Question

Can someone please show what the graph of
y=-2+tanx would look like?

Answer 1

do you have a graphing calculator?

Answer 2

if not, then I recommend downloading geogebra

Answer 4

i do, but it does not show it the way i am graphing it. do you know how to graph this function by hand?

Answer 5

to do it by hand, you can start with the graph of tan(x), then shift it down 2 units

or you can plot a series of points and connect them with a curve...but you have to keep in mind of the asymptotes

Answer 6

are you supposed to shift it down two units or half that, therefore moving it down one unit?

Answer 7

no it's 2 units

Answer 8

-2+tan(x) is the same as tan(x) - 2

so if y = tan(x)

then you're essentially saying y - 2 (ie take each y value and subtract 2 from it)

Answer 9

okay thanks :)
