1. Drawing Graphs The parabola x Example y
Draw the graph of y = x2 for values of x between -4 and 4 x –4 –3 –2 –1 1 2 3 4 y

2. Draw on the same set of axes the graphs of a) y = 2x2 b) y = 3x2
Example
Draw on the same set of axes the graphs of
a) y = 2x2
b) y = 3x2
c) y = ½x2
for values of x between -4 and 4 x –4 –3 –2 –1 1 2 3 4 a) y b) c)

3. Draw the graph of y = x2 + 2x for x between -4 and 3 x
Example
