## What is the minimum value of the function?

The minimum value of a function is the lowest point of a vertex. 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.

## What are the key points in a graph?

They are the three x-intercepts, the maximum point, and the minimum point.

## How do you say than in ASL?

“than” American Sign Language (ASL) THAN: Your dominant hand (which is the right hand for most people) moves down past your non-dominant hand. The dominant hand whacks the tip of the non-dominant hand a bit while moving downward.

## What are the characteristics of a function?

A function is a relation in which each possible input value leads to exactly one output value. We say “the output is a function of the input.” The input values make up the domain, and the output values make up the range.

## What is a function and why is it important?

Because we continually make theories about dependencies between quantities in nature and society, functions are important tools in the construction of mathematical models. In school mathematics, functions usually have numerical inputs and outputs and are often defined by an algebraic expression.

## How do you identify the key features of a function?

Key features include: intercepts; intervals where the function is increasing, decreasing, positive, or negative; relative maximums and minimums; symmetries; end behavior; and periodicity.

## 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.

## What is on to function?

A function f: A -> B is called an onto function if the range of f is B. In other words, if each b ∈ B there exists at least one a ∈ A such that. f(a) = b, then f is an on-to function. An onto function is also called surjective function.

## What does the graph of a function represent?

The graph of the function is the set of all points (x,y) in the plane that satisfies the equation y=f(x) y = f ( x ) . The y value of a point where a vertical line intersects a graph represents an output for that input x value.

## How does graphing help in real life?

A graph can be a very effective tool in presenting visual information rather swiftly. Even students can use a graph as it is something simple to draw. Dot, lines and a little bit of knowledge can go a long way. When measuring seismic waves a graph can identify any faulty areas and help to keep track of the situation.

## What inequality sign is maximum?

Inequality Word Phrases

A | B |

maximum | less than or equal to |

smaller than | less than |

above | greater than |

not to exceed | less than or equal to |

## What defines a function?

A technical definition of a function is: a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

## What are the key features of a quadratic function?

Three properties that are universal to all quadratic functions: 1) The graph of a quadratic function is always a parabola that either opens upward or downward (end behavior); 2) The domain of a quadratic function is all real numbers; and 3) The vertex is the lowest point when the parabola opens upwards; while the …

## What is the sign for minimum?

For ordering, minimum means ‘less than or equal to’, which is symbolized in some/many mathematics disciplines as ≤. List A = [1 0 1 0], List B = [1 1 0 0]; List (A[i]≤B[j] = [1 0 0 0]. For Boolean algebras, just multiply the two lists to generate the minimums: List (A[i]*[j] = [1 0 0 0].

## Why is function important in real life?

understand various types of patterns and functional relationships; use symbolic forms to represent and analyze mathematical situations and structures; use mathematical models and analyze change in both real and abstract contexts.

## How do you know if the graph is a function?

Use the vertical line test to determine whether or not a graph represents a function. If a vertical line is moved across the graph and, at any time, touches the graph at only one point, then the graph is a function. If the vertical line touches the graph at more than one point, then the graph is not a function.

## What is minimum mean?

Minimum means the lowest amount or level of something. Minimum can be a noun or an adjective and it has several more specific meanings, all of which are related in some way to its primary meaning. When minimum is used as a noun, its plural can be minimums or, less commonly, minima.

## What is the difference between characteristics and functions?

As nouns the difference between characteristic and function is that characteristic is a distinguishable feature of a person or thing while function is what something does or is used for.
