How To Find The Maximum Value Of A Quadratic Function?

How do you find the maximum value of a quadratic equation?

If you are given the formula y = ax2 + bx + c, then you can find the maximum value using the formula max = c – (b2 / 4a).

If you have the equation y = a(x-h)2 + k and the a term is negative, then the maximum value is k.

How do you find the minimum and maximum of a quadratic function?

You can use a graph to identify the vertex or you can find the minimum or maximum value algebraically by using the formula x = -b / 2a. This formula will give you the x-coordinate of the vertex. Simply replace the x in your original equation with the value of the x-coordinate and then solve for y.

How do you find the minimum value of a quadratic equation?

If your quadratic equation has a positive a term, it will also have a minimum value. You can find this minimum value by graphing the function or by using one of the two equations. If you have the equation in the form of y = ax^2 + bx + c, then you can find the minimum value using the equation min = c – b^2/4a.
