Graph
Explanation:
The important parts to graph y are:
a. x-coordinate of vertex and axis of symmetry:
y-coordinate of vertex:
b. y-intercept. Make x = 0 --> y = 4
x-intercepts. Make y = 0 and solve
Since D = 4 - 96 < 0, there are no x-intercepts (no real roots). The parabola is completely above the x-axis and it opens upward (a > 0).
