## What is a local minimum on a graph?

A local maximum point on a function is a point (x,y) on the graph of the function whose y coordinate is larger than all other y coordinates on the graph at points “close to” (x,y).

…

Similarly, (x,y) is a local minimum point if it has locally the smallest y coordinate..

## What is a function value?

A function is an equation that has only one answer for y for every x. A function assigns exactly one output to each input of a specified type. It is common to name a function either f(x) or g(x) instead of y. f(2) means that we should find the value of our function when x equals 2. Example.

## How can you tell if a graph is a function?

Inspect the graph to see if any vertical line drawn would intersect the curve more than once. If there is any such line, the graph does not represent a function. If no vertical line can intersect the curve more than once, the graph does represent a function.

## What is the maximum point?

Maximum, In mathematics, a point at which a function’s value is greatest. If the value is greater than or equal to all other function values, it is an absolute maximum. If it is merely greater than any nearby point, it is a relative, or local, maximum.

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

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.

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

To find the critical numbers of this function, here’s what you do.Find the first derivative of f using the power rule.Set the derivative equal to zero and solve for x. x = 0, –2, or 2. These three x-values are the critical numbers of f.

## What are local minimum values?

The local maxima of the function The local minima of the function. A point x x x is a local maximum or minimum of a function if it is the absolute maximum or minimum value of a function in the interval ( x − c , x + c ) (x – c, \, x + c) (x−c,x+c) for some sufficiently small value c c c.

## What is not a function?

A function is a relation in which each input has only one output. In the relation , y is a function of x, because for each input x (1, 2, 3, or 0), there is only one output y. x is not a function of y, because the input y = 3 has multiple outputs: x = 1 and x = 2.

## What is the range for?

The Range is the difference between the lowest and highest values. Example: In {4, 6, 9, 3, 7} the lowest value is 3, and the highest is 9. So the range is 9 − 3 = 6.

## What is maximum and minimum of a function?

A maximum is a high point and a minimum is a low point: In a smoothly changing function a maximum or minimum is always where the function flattens out (except for a saddle point).

## What is the maximum value of a function?

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