science space and astronomy# How do you find the maximum value of a quadratic function?

**maximum value**using the formula

**max**=c- (b2 / 4a). If you have the equation y = a(x-h)2 + k and theaterm is negative, then the

**maximum value**is k.

Keeping this in view, how do you find the minimum value of a quadratic equation?

If your **quadratic equation** has a positive aterm,it will also have a **minimum value**. You can **find**this**minimum value** by graphing the function or by using oneofthe two **equations**. If you have the **equation** intheform of y = ax^2 + bx + c, then you can **find theminimumvalue** using the **equation min** = c -b^2/4a.

**Maximum, In mathematics**, a point at whichafunction's value is greatest. If the value is greater than orequalto all other function values, it is an absolute

**maximum**. Ifit is merely greater than any nearby point, it isa relative, orlocal,

**maximum**.

Thereof, what is the maximum value of a function?

The **maximum value of a function** is the placewherea **function** reaches its highest point, or vertex, on agraph.For instance, in this image, the **maximum value** ofthe**function** is y equals 5. Practically, finding the**maximumvalue of a function** can be used to determine**maximum**profit or **maximum** area.

A continuous **function** may assume a**maximum**at a single point or may have maxima at a number ofpoints. Aglobal **maximum** of a **function** is the largestvalue inthe entire range of the **function**, and a local**maximum**is the largest value in some localneighborhood.
