Let $f(x)$ be the function that connects the points $a = (-1,0),$  $b = (0,1),$  $c = (1,0),$   and $d = (2,1)$ by line segments in alphabetical order, as shown in the graph. (a) The transformation $$\textstyle y = -4.5f\!\left(\frac{x}{2.5}\right)$$ takes the points $a,$  $b,$  $c$  and $d$ on the graph of $y = f(x)$ to the following points: help (points) A = B = C = D = (b) Without using a calculator, draw a graph of $y = -4.5f\!\left(\frac{x}{2.5}\right)$ 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, B, C and D to shift and scale the blue graph (the gray graph is just for reference).
