Plug in zero for x and you get your point where the graph starts. With a negative, this means that the graph is pointing down. You can also figure it out by plugging in points for x and find y.

plugging zero in for x, will give you the y intercept. where the graph of the function intersects the y axis but other than that he's right^

First, yes the graph will point down since there is a NEGATIVE in front of x^2 when i click the pix, only one graph

no because it has to be pointing down

Since the coefficient is negative; the graph HAS to point down. This is a parabola in a frown so options are the first (11_1_0) graph and last graph (11 _ 1_3)

so now - find y intercept (set x = o and solve for y) what do you get for y intercept

once you determine that - find the graph with the parabola going through that point
