Question

How do you graph `y=3sin(1/2x)`?

Answer 1

If we can draw the graph of
`y=f (x)` then the graph of `y=af (bx)` can be derived from the graph of `y=f (x)`
Here `a` is the measure of stretching in the `y` direction and `b` is the measure of compression in the `x` direction.

Explanation:

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