The graph of y = 8cosx is ________ than the graph of y = cosx.

wider (stretched out horizontally)

narrower (squished horizontally)

The graph of y=(1/3)sinx is _________ than the graph of y=sinx.

wider (stretched out horizontally)

narrower (squished horizontally)

The graph of y = 2cos(4x) is __________ than the graph of y = 2cos(x).

narrower (squished horizontally)

wider (stretched out horizontally)

The graph of y=2sin(1/2 x) is __________ than the graph of y=2sin(x).

wider (stretched out horizontally)

narrower (squished horizontally)

Distance from rest (midline) to crest

Double the distance from rest (midline) to crest

The graph of y = -8sin(3x)+5 is shifted...

Trick question - there's no midline shift

This is a good little review, but you'll also have to graph by hand (like on the last practices). That means you should do the assignments since these are just multiple choice questions. But, here's one to try: Sketch $$f\left(x\right)=-2\sin\left(3x\right)-4$$

It is reflected, has an amplitude of 2, has a period of $$\frac{2\pi}{3}$$ , and is vertically shifted 4 units down

It is reflected, has an amplitude of 2, has a period of 3, and is vertically shifted 4 units down

It is reflected, has an amplitude of 2, has a period of 3, and is vertically shifted 4 units up

It is reflected, has an amplitude of 2, has a period of $$\frac{2\pi}{3}$$ , and is vertically shifted 4 units up

Here's another one to try: Sketch $$f\left(x\right)=-3\cos\left(6x\right)+2$$

It starts at -1, has a period of $$\frac{\pi}{3}$$

It starts at -3, has a period of $$\frac{\pi}{3}$$

It starts at -1, has a period of 6

It starts at 2, has a period of $$\frac{\pi}{3}$$
