Assign the values for
x from
−5 to
5 and we get the corresponding
y values.Then tabulate as follows:
x | −5 | −4 | −3 | −2 | −1 | 0 | 1 | 2 | 3 | 4 | 5 |
y | −25 | −16 | −9 | −4 | −1 | 0 | 1 | 4 | 9 | 16 | 25 |
Plot the points (−5,−25),(−4,−16),(−3,−9),(−2,−4),(−1,−1),(0,0),(1,−1),(2,−4),(3,−9),(4,−16),(5,−25) on the graph sheet and join the points by a smooth curve.This curve is called parabola.
