You can find the x-coordinate of it's vertex by taking it's derivative and solving for zero:
y = -3x2 + 12x - 5
y' = -6x + 12
0 = -6x + 12
6x = 12
x = 2
Now that we have it's x coordinate, we can plug it back into the original equation to find it's y coordinate:
y = -3x2 + 12x - 5
y = -3(2)2 + 12(2) + 5
y = -12 + 24 + 5
y = 17
So the vertex of the parabola y = -3x2 + 12x - 5 occurs at the point (2, 17).
What else can I help you with?
How do you find the axis of symmetry and vertex of y equals x squared plus 6x plus 10?
By completing the square y = (x+3)2+1 Axis of symmetry and vertex: x = -3 and (-3, 1) Note that the parabola has no x intercepts because the discriminant is less than zero

nice attempt :) at least you couldve said some stupid crips rolling in 6 fo's with dicks or something, which ive herd before the answer is -6 -apex-
What is the vertex for the parabola y equals x squared plus 4x plus 5?
The vertex of a parabola is the minimum or maximum value of the parabola. To find the maximum/minimum of a parabola complete the square: x² + 4x + 5 = x² + 4x + 4 - 4 + 5 = (x² + 4x + 4) + (-4 + 5) = (x + 2)² + 1 As (x + 2)² is greater than or equal to 0, the minimum value (vertex) occurs when this is zero, ie (x + 2)² = 0 → x + 2 = 0 → x = -2 As (x + 2)² = 0, the minimum value is 0 + 1 = 1. Thus the vertex of the parabola is at (-2, 1).
If x equals 10 and y equals 10 then 9x plus 8y equals?
If x equals 10 and y equals 10, then 9x plus 8y equals 170.
Tell whether the graph opens up or down Find the coordinates of the vertex Write an equation of the axis of symmetry for the equation y equals 2x2 plus 3x plus 6?
y = 2x2 + 3x + 6 Since a > 0 (a = 2, b = 3, c = 6) the graph opens upward. The coordinates of the vertex are (-b/2a, f(-b/2a)) = (- 0.75, 4.875). The equation of the axis of symmetry is x = -0.75.
