For the quadratic function, f\left(x\right)=-2x^{2\ }+5x+1, identifiy the axis of symmetry and the vertex

• NO SOLUTION

Given the quadratic equation, 3x^2-4x+5=14, determine the discriminant and describe the solutions.

If the standard form of a quadratic function is f\left(x\right)=-2x^2+12x-17 which of the following functions represents the vertex form and the transformation that took place from the parent function?

Write a quadratic equation for a parabola with attributes: axis of symmetry is x=3, focus is (3,7), and directrix is y = 3.

Theo is kicking field goals. His football is kicked in the air and follows the path defined by h=-\frac{1}{2}t^2+8t, where t is the time in seconds and h is the height in meters.  Desmond is in the stands of the stadium behind the goal posts.  He is at a height of 45 meters and is descending the stairs at a rate of 2.5 meters per second.  Which system of equations correctly identifies how to determine and how high the ball will be when it and Desmond intersect?
