For questions 1 and 2, use integer values of x from –3 to 3 to graph the equation.

Question

1.  
y = –2x2 + 3  (1 point)

Answer 1

y = -2 x^2 + 3
well that is a parabola.
for big - or + x, it is huge negative so opens down, sheds water.
It is symmetric about x = 0 so that is the vertex (0,3)
Now try your numbers
if x = -3
y = -2(-3)(-3) + 3
y = -18 + 3
y = -15
etc
(same y for x = + 3 of course)
