MY NOTES ASK YOUR TEACHER To graph the function f, we plot the points (x, f(x) > ) in a coordinate plane. To graph f(x) = x - 2, we plot the following points. O ( x, x - 3) O ( x, 0) O ( x, x2 - 2) O ( x, 1) O ( x, 2x) So the point (5, is on the graph of f. The height of the graph of f above the x-axis when x = 5 is Complete the table.
