a. y=tan((8x)/3 - (8π)/15) -2

b. y=tan((8x)/3 + (8π)/15) -2

c. y=tan((16x)/3 +(3π)/80) -2

d. y=tan((8x)/3 - (3π)/40) -2

I think it is A... or B?

**Reiny**, Friday, May 29, 2009 at 7:28pmpersonally, I prefer to write trig functions with the k factor outside the bracket. That way the sphase shift is immediately obvious.

so my first choice would have been

y = tan (8/3)(x + π/5) - 2

which after expanding, is the same as B
