Question 1 For the graph of the function y = cosx, the statement that is not true is Not yet answered Select one: Fir Marked out of O a. The period can be found by determining the horizontal distance between any two consecutive X-intercepts. 1.00 Flag O b. The period can be found by determining the horizontal distance between (-T, - 1) and (1, - 1). question O c. The amplitude can be found by dividing the vertical distance between (It, - 1) and (2nt, 1) by 2. O d. The amplitude can be found by determining the vertical distance from a maximum point to the X-axis.
