Clue from f(x)=-3x^2;
it will graph upside down due to the negative
...
y intercept is 0
Plot (0,0)
...
x intercepts are when y = 0
0 = -3x^2
x^2 = 0
x = 0
Plot (0,0)
...
choose random values for x and solve for y
If x is 1
y = -3(1)^2 = -3
Plot(1,-3)
If x is 2
y = -3(2)^2 = -12
Plot (2,-12)
If x is -1
y = -3(-1)^2 = -3
Plot (-1,-3)
If x is -2
y = -3(-2)^2 = -12
Plot (-2,-12)
and so on
