Geno's method will work....but here's something that might be easier........ using...... y^2 = 2x
Divide both sides by 2...so we have
y^2/2 = x
Now, nstead of selecting "x" values, just select a few y values.....I suggest 0, 2, 4, 6 and -2,-4, -6 ....and find the associated "x" for each one......we don't have to take any square roots that way...
If you do this correctly...you should end up with parabola facing to the "right" with its vertex at the origin !!!
You can do this by plotting points:
x | y Complete this table; some of the values for x will have no values for y.
_______ Also, because you need to find square roots, many of these will have
-9 | two answer, one + and one -.
-4 |
-1 |
0 |
1 |
4 |
9 |
