Graph in the given window • Y = (x2+ 2) + (x -5) [-4., 2] by [-3, 4] • Which is the best window for the equation y = a. Zoom decimal b. zoom standard c. zoom out Answer:C • The function y = .04x4 – 0.4x2 + 15 is w-shaped. Find a window setting that allows you to clearly see the w-shape. Answer: something like [-5, 5] x [-10, 20]
Solve equations • Solve for x: 5x – 12 = 3(4x +1) answer: x = - 15/7 or - 2.142 • Solve for m: answer: m = 20 • Solve for w: answer: x = 41/7 or 5.85 • Solve for x: 3x + 4y = -7 y = -3/4 x – 7/4 or y = -0.75x – 1.75
