Question

Identify the period, phase shift and vertical shift of y=3tan(x-pi/2) +1

thank you so much :)

Answer 1

what parts can you identify?

Answer 2

Hmm, I'm not sure. we go right by pi/2 right?

Answer 3

good, so that shifts the phase

Answer 4

since there is no number multiplying the x, it retains its basic peroidicity

Answer 5

and since y = k differs from y=k+1, by 1 ... what would you say that effects?

Answer 6

the period?

Answer 7

no, the period is inside of the trig function; let k represent that trig function to clean things up

Answer 8

when k=0, what the affect on: y=k, and y=k+1
