20) For the graph of the function y= cost, the statement that is not true. at the amplitude can be found by dividing the vertical distance between (o,1) and (TT, -1 ) by 2 b) the period can be Found by determining the horizontal distance between any two consecutive X-ints. () the period can be Found by determing the horizontal distance between cor) and (2TT, 1 ) d ) the amplitude can be found by determining the vertical distance from a maximum point to the x-axis
