how do you dilate this function vertically by -2?

Answer:
Students manipulate functions and relate amplitude, period, horizontal and vertical ... Students identify the relationship between vertical dilation and amplitude.do to the graph of. f. (. x. ) ? shrinks it horizontally. stretches it horizontally. shrinks it vertically. stretches it vertically.Students will be able to. understand horizontal dilations of the function f ( x ) : f ( a x ) corresponds to a horizontal dilation of scale factor 1 a ,; when a < 1 ...
