15. [-/15 Points] DETAILS SPRECALC7 2.2.001. To graph the function ?, we plot the points (x. (0 v )in a coordinate plane. To graph ((x) = x2 - 2, we plot the following points. O (x, 2x) (x, 0) O ( x, x 2 - 2) O ( x, 1) O (x x - 3) So the point (5, 0 is on the graph of f. The height of the graph of f above the x-axis when x = 5 is |0 Complete the table. X 1(x) = x2- 2 (x, y) -2 -1 0 2 Sketch a graph of f
