What do you think the graph of \(y = \cos 2x^\circ\) would look like? amplitude = 1, so the distance between the maximum and minimum values is 2 number of waves = 2 (period is 360˚ ÷ 2 = 180 ...

Quadratic graph lines are U- or Ո-shaped ... Draw and label the axes to include the minimum and maximum values of \(x\) and \(y\). The coordinates \((x, y)\) are read from the table and plotted ...
