Question 645268
can someone show me how to go about graphing this parabola y=3/4x^2
-------------
Same as most.
Pick values for x and find y.
Plot the points.
Draw a curve thru them.
---------
{{{y = 3x^2/4}}}
x = 0, y = 0 --> (0,0)
x = 1, y = 0.75 --> (1,0.75)
Notice that +x and -x give the same y.
----------
Use Excel to make a table of points.

Even better,
