Options
A) The graph is a parabola with a minimum point.
B) The graph is a parabola with a maximum point.
C) The point (2, 2) lies on the graph.
D) The point (1, 6) lies on the graph.
E) The graph crosses the xaxis at x = −4and x =1.
F) The graph crosses the xaxis at x = −1and x =4.
G) The graph crosses the yaxis at y = −4.

because the sign of the second degree term of the polynomial (x^2) is positive, its graph is a parabola with a minimum.
So A is true.
if you fill in 1 and 4 in the equation, you get 0, ergo the graph crosses the xaxis at 1 and 4. So F is true.
For x = 0, y= 4, so the graph crosses the yaxis at 4, so G is also true.
