Amplitude is

The period is always given by

The graph has endured a reflection over the y-axis, because the leading coefficient, or

When graphing, remember that sinusoidal functions are cyclic, or they repeat to infinity. The shape isn't a straight line, so there should always be a curve, and you pencil should never leave the page when drawing them.

In the end, you should get the following graph
