Please help Hillary's teacher asked her to write a description of the transformations to the parent cosine function that would result in this function h(x) = - 3cos(2x - pi) + 4 Which statements in her description are true about function h To create the graph of function Hi the graph of the parent function is horizontally compressed by factor of Then it undergoes a phase shift left pi/2 unitsNext it is vertically compressed by a factor of - 3 and vertically shifted up 4 units The period of function half the period of the parent functionand it has an amplitude 3 units greater than that of the parent function
