Answer 1

I'll try.

Answer 2

i'll try too

Answer 3

I know it's either C or D due to the period, just don't know if it's negative or positive

Answer 4

I think that you r right but let her confirm

Answer 5

For the period, think what it would be if it was a normal tan(x) graph, pi.

As tan(4x) has a horizontal squash of scale factor 4, the period is pi/4.

Then think about phase shift, using f(x)=tan(x)
So f(x-pi/3)=tan(x-pi/3) which is a simple translation pi/3 to the right (positive x axis)

Notice that all of these only depend on what's happening to the x value, and the 3 which affects the y value effectively does nothing in this context.

Answer 6

So it would be positive.

Answer 7

Correct so I do believe you are correct

Answer 8

Thank you both so much!
