(Change the location of graphs) Shift Graph shift function helps students grasp the relationship between an equation and its graph. Shift the graph’s location without changing its shape, and the change is immediately reflected in the equation on the right side of the display. Example 2 When the graph of y = x is shifted downward, how does this affect the equation? Key Operation Display Notes Enter SHIFT/CHANGE mode. SHIFT/CHANGE 1 If is not already SHIFT highlighted press . ] Select shift. Cu
