Asked by Nighty
What is the y-intercept, the equation of the axis of symmetry, and the x-coordinates of the vertex?
Can you also make table of values that includes the vertex?
f(x) = 3x^2 + 8x

the vertex (and also the axis of symmetry) lies on the line x = -b/2a
That is, x = -8/6 = -4/3
The y=intercept is clearly at (0,0)
