# How do you sketch #y = 3 sin 2 (x-1)#?

##### 1 Answer

graph{3sin(2(x-1)) [-10, 10, -5, 5]}

#### Explanation:

If we consider

graph{3sinx [-10, 10, -5, 5]}

We will look at C next, this is the movement of the graph left or right, where a negative C value moves the graph to the right. So we move the whole graph 1 to the right in this case.

graph{3sin(x-1) [-10, 10, -5, 5]}

Finally B is stretching the graph parallel to the x axis by a factor of

So in your case B = 2, so

Then graphing this:

graph{3sin(2(x-1)) [-10, 10, -5, 5]}
