You can put this solution on YOUR website! How do you sketch a graph of y=3x^2?
:
Choose values for x and find y. Let's say -3 to + 3
:
Substitute -3 for x and find y like this:
y = 3(-3)^2
y = 3*9
y = +27
:
Do the same with -2, -1, 0, 1, 2, 3, a table of values should look like this:
x | y
------
-3|+27
-2|+12
-1|+3
0 | 0
+1|+3
+2|+12
+3|+27
:
Plot these x,y coordinates. The graph should look like this:
