And here is your Shmoop du jour.

00:04

Which is the graph of y equals 4 sine x ?

00:08

And here are your options.

00:13

Okay, well let's break this problem down.

00:16

We have 4 and sine of x...

00:18

That's it. The 4 refers to the amplitude

00:22

of the sine curve or how high and low the graph can go.

00:25

When we look at all the answer choices only one actually has this

00:29

amplitude of 4. Big high up thingy here and the low thingy there. That's amplitude.

00:36

So it's option C.

00:37

As further confirmation options C is a normal sine curve

00:41

besides from its amplitude. So that's it... piece a cake. It's option C.
