## How do you find the maximum and minimum of a parabola?

We can identify the minimum or maximum value of a parabola by identifying the y-coordinate of the vertex. 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.**

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

Finding max/min: There are two ways to find the absolute maximum/minimum value for f**(x) ax2 + bx + c: Put the quadratic in standard form f(x) a(x u2212 h)2 + k, and the absolute maximum/minimum value is k and it occurs at x h. If a x26gt; 0, then the parabola opens up, and it is a minimum functional value of f.**

## What is the maximum or minimum point of a parabola called?

vertex

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

Finding max/min: There are two ways to find the absolute maximum/minimum value for **f(x) ax2 + bx + c: Put the quadratic in standard form f(x) a(x u2212 h)2 + k, and the absolute maximum/minimum value is k and it occurs at x h. If a x26gt; 0, then the parabola opens up, and it is a minimum functional value of f.**

## How do you find maximum and minimum values?

Vertical parabolas give an important piece of information: When the parabola opens up, **the vertex is the lowest point on the graph called the minimum, or min. When the parabola opens down, the vertex is the highest point on the graph called the maximum, or max.**

## How do you find the maximum value of a function?

If you have the graph, or can draw the graph, the maximum is just the y value at the vertex of the graph. If you are unable to draw a graph, there are formulas you can use to find the maximum. If you are given the formula y ax2 + bx + c, then you can find the maximum value using the **formula max c – (b2 / 4a)**

## How do you find the minimum of a function?

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**

## What is the maximum and minimum of a parabola called?

The highest or lowest point on a parabola is called **the vertex. The parabola is symmetric about a vertical line through its vertex, called the axis of symmetry. The figure below shows a parabola opening up with vertex (0.75, 0.875) and axis of symmetry x 0.75.**

## What is the minimum or maximum of a quadratic function called?

The graph of a quadratic function is a U-shaped curve called a parabola. The extreme point ( maximum or minimum ) of a parabola is called **the vertex, and the axis of symmetry is a vertical line that passes through the vertex.**

## What are the points called on a parabola?

A parabola is set of all points in a plane which are an equal distance away from a given point and given line. The point is called **the focus of the parabola and the line is called the directrix. The focus lies on the axis of symmetry of the parabola.**

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

Finding max/min: There are two ways to find the absolute maximum/minimum value for **f(x) ax2 + bx + c: Put the quadratic in standard form f(x) a(x u2212 h)2 + k, and the absolute maximum/minimum value is k and it occurs at x h. If a x26gt; 0, then the parabola opens up, and it is a minimum functional value of f.**

## How do you find the maximum of a quadratic function?

If your equation is in the form ax2 + bx + c, you can find the maximum by using the equation: **max c – (b2 / 4a).**

## How do you find the minimum of a quadratic function?

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**

## What is the maximum and minimum of a quadratic function?

The graph of a quadratic function is a U-shaped curve called a parabola. If the **parabola opens up, the vertex represents the lowest point on the graph, or the minimum value of the quadratic function. If the parabola opens down, the vertex represents the highest point on the graph, or the maximum value.**

## How do you find the maximum value?

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 value of a variable?

For a function of one variable, f(x), we find the local maxima/minima by differenti- ation. Maxima/minima occur when **f (x) 0. x a is a maximum if f (a) 0 and f (a) x26lt; 0; u2022 x a is a minimum if f (a) 0 and f (a) x26gt; 0; A point where f (a) 0 and f (a) 0 is called a point of inflection.**
