Let $f(x) = \sin\!\left(\frac{\pi }{4}\!\left(x-1\right)\right)-2 .$ (a) The sinusoidal function $f(x)$ has amplitude = midline at y = period = horizontal shift = (b) Without using a calculator, draw a graph of $y = f(x)$ on paper by using your answers from the previous part. Using the interactive applet to the right, enter your graph by clicking and draging the points A and B to shift and scale the sinusoidal function.
