How do you write # y=3x^2-12x+17# in vertex form and identify the vertex, y intercept and x intercept?
x of vertex:
y of vertex:
To find y-intercept, make x = 0 -> y = 17
To find x-intercept solve
D = 144 - 204 = -60 < 0.
There are no x-intercepts. The parabola graph doesn't intersect the x-axis. It is completely above the x-axis.
