Answer 4

Where the denominator is 0, you have a vertical asymptote.

Answer 5

Okay... I've been looking at these graphs

Answer 6

Not y = sinx

Answer 7

But it seems like y = cotx could be one?

Answer 8

cot is cos/sin so where the sin is 0 there will be asymptotes. Where is the sin = 0?

Answer 9

D. II and IV only

Answer 10

Good for you!!!

Answer 11

Wait, another one. What is the amplitude of the sinusoid's graph? y = -4 sin 3x

Answer 12

Answer 13

is it +4?
