Question 369508
what is the x and y values of the function y=-2x^3 and how do you graph it?
----------------
There are an infinite number of x and y values.  The question makes no sense, plus the noun and verb don't match.
---------------
To graph it, pick values of x and find y.
Plot the points.
Draw a smooth curve thru them.
--------------
You can use Excel to do the calculations.
eg:
x = 0--> y = 0 (0,0)
x = 1--> y = -2 (1,-2)
etc
