(Section 1.8: x=fy()) 1.8.7 The “coordinate shift method” from Section 1.4, Part F still applies: Example 2 (Coordinate Shifting and Intercepts)We will translate the parabola on the left so that its turning point (its vertex) is moved from 0, 0to ±4, 1; that is, it is moved 4 units to the leftand 1 unit up. Graph of x=y2Graph of x+4=y±12, or x=y±12±4Look at the graph on the right. As usual, • To find the x-intercept, substitute y=0into an equation, and solve for x.
