lucaz · Answer

any hint?

loser66 · Answer

to tangent function: no amplitude
period: take difference between 2 x-intercept points

lucaz · Answer

period is pi/4?

loser66 · Answer

pi/2

lucaz · Answer

right, it was 4/8..

loser66 · Answer

:)

lucaz · Answer

and the amplitude, the form of the function is Atan(Bx)+C
if there is no amplitude what do I do? to find A?

loser66 · Answer

NO amplitude for any tangent function. period

lucaz · Answer

just remove A from the function?

loser66 · Answer

I don't get what you mean by finding A.

loser66 · Answer

lucaz · Answer

well, that's what the problem says, function of tangent is in the form Atan(Bx)+C

lucaz · Answer

you say no amplitude because it's infinite?

loser66 · Answer

loser66 · Answer

to any question about the amplitude of tangent function, the answer is : no amplitude.

lucaz · Answer

i think it's the case of -1, to flip the graph?

loser66 · Answer

what do you mean by "flip" the graph? when you "lie" it down, you have arctan , which is another topic.!!!

lucaz · Answer

like the graph of sin(x) and -sin(x)

loser66 · Answer

oh NO!! - sin (x) is image of sinx through x-axis, or reflecting of sinx through x-axis, 
Moreover, sin/ cos has amplitude, when tangent doesn't

lucaz · Answer

right..

I will try to solve the problem, thanks!
