Sketching Graphs

Sketching Graphs. Information. Plotting graphs. How could the graph of y = x 3 – 7 x + 2 for the interval –3 ≤ x ≤ 3 be plotted?. By creating a table of points, plotting them and joining them with a smooth curve.

Review of Simple Sketching

Review of Simple Sketching. Last lesson we started reviewing the use of algebra for simple quadratic graph sketching. Ex1: Sketching y = x 2 + 2 x – 3 without using your graphic calculator. for TP let x = Sub into equation y = (-1) 2 + 2 -1 – 3 y = -4 So TP = (-1,-4).
