How do you find the axis of symmetry and vertex point of the function: #y = 3x^2 - 7x - 8#?
Since this is a parabola with axis of symmetry parallel to the
To find the minimum, you could plug the formula, but I prefer to avoid them, if you can get them by reasoning :)
So, to find the minimum, simply differentiate the formula and find the root of the derivative:
So, at this point, we already know that the axis of symmetry is the line
Finding the vertex is even simplier: since it is a point on the parabola, and you know the
