Question: Can A Discrete Function Be Continuous?

How do you tell if a function is discrete or continuous?

In Plain English: A continuous function allows the x-values to be ANY points in the interval, including fractions, decimals, and irrational values.

In Plain English: A discrete function allows the x-values to be only certain points in the interval, usually only integers or whole numbers..

How do you determine if a domain is discrete or continuous?

A discrete domain is a set of input values that consists of only certain numbers in an interval. A continuous domain is a set of input values that consists of all numbers in an interval. Sometimes the set of points that represent the solutions of an equation are distinct, and other times the points are connected.

Is Money discrete or continuous?

A continuous distribution should have an infinite number of values between $0.00 and $0.01. Money does not have this property – there is always an indivisible unit of smallest currency. And as such, money is a discrete quantity.

Is age continuous or discrete?

Age is measured in units that, if precise enough, could be any number. Therefore the set they come from is infinite. For example, someone could be 22.32698457 years old or 22.32698459 years old. We could be infinitly accurate and use an infinite number of decimal places, therefore making age continuous.

Is time a discrete or continuous variable?

Time is a continuous variable. You could turn age into a discrete variable and then you could count it. For example: A person’s age in years.

Is hours of sleep discrete or continuous?

Amount of sleep is a variable. 3, 5, 9 hours of sleep are different values for that variable. Variables can be continuous or discrete.

What is discrete math example?

Examples of structures that are discrete are combinations, graphs, and logical statements. Discrete structures can be finite or infinite. Discrete mathematics is in contrast to continuous mathematics, which deals with structures which can range in value over the real numbers, or have some non-separable quality.

Is population a discrete or continuous variable?

Population counts are typically referred to as discrete or quantitative data. Why is population density a continuous data type when it is typically measured for aggregate areas such as census tracts or districts/neighbourhoods (ie, it can’t be measured at any point on a surface like gradient or temperature).

Is a phone number discrete or continuous?

It is also a discrete variable because one can simply count the number of phone calls made on a cell phone in any given day. The possible numbers are only integers such as 0, 1, 2, … , 50, etc. (Some of you probably make a lot of cell phone calls.)

How difficult is discrete math?

Discrete math is something that definitely takes some getting used to. The actual calculations are not more difficult. The difficult part is the thought process and thinking logically.

Do I need discrete math for algorithms?

Yes. Developing algorithms requires knowledge of certain subtopics of “Discrete Mathematics”, but many people learn and understand these concepts without taking a formal course in DM. If you are learning algorithms, you are already applying discrete mathematics.

What’s the difference between continuous and discrete?

Discrete data is information that can only take certain values. Continuous data is data that can take any value. … Height, weight, temperature and length are all examples of continuous data.

Is blood type continuous or discrete?

Blood type is not a discrete random variable because it is categorical. Continuous random variables have numeric values that can be any number in an interval. For example, the (exact) weight of a person is a continuous random variable.

Can a graph be discrete and continuous?

Discrete functions have scatter plots as graphs and continuous functions have lines or curves as graphs. If a continuous function has a graph with a straight line, then it is referred to as a linear function.

Is blood pressure discrete or continuous?

Examples of continuous variables are body mass, height, blood pressure and cholesterol. A discrete quantitative variable is one that can only take specific numeric values (rather than any value in an interval), but those numeric values have a clear quantitative interpretation.

Why is it called discrete math?

“Discrete Math” is not the name of a branch of mathematics, like number theory, algebra, calculus, etc. Rather, it’s a description of a set of branches of math that all have in common the feature that they are “discrete” rather than “continuous”. … logic and Boolean algebra.
