y X (a) The graph of the blue function is y=-34cos(90x). Report the phase shift* of the red function. Do not enter an approximate value. To enter a value like 27, type 2 *pi. While there are many correct answers, give the smallest value for the phase shift that produces the red function. The phase shift of the red shifted upside down cosine function is Number to the Click for List *The phase shift is what fraction of the period of the blue graph has been shifted to produce the red graph, if the red graph were to have a period of 2x. (b) If the graph of the blue function is y=-34cos(90x), what is the equation of the red function? Do not include approximate values. (See above how to enter z.)
