Relations can be displayed as **a table, a mapping or a graph**. In a table the x-values and y-values are listed in separate columns. Each row represents an ordered pair: Displaying a relation as a table.

A one-to-one relationship exists when each row in one table has only one related row in a second table. For example, **a business might decide to assign one office to exactly one employee**. Thus, one employee can have only one office.

**How to Determine if a Relation is a Function?**

- Examine the x or input values.
- Examine also the y or output values.
- If all the input values are different, then the relation becomes a function, and if the values are repeated, the relation is not a function.

The representation of a relation on a rectangular coordinate plane, as illustrated above, is called a graphA visual representation of a relation on a rectangular coordinate plane.. **Any curve graphed on a rectangular coordinate plane represents a set of ordered pairs and thus defines a relation**.

real numbers

In a one-to-many relationship, one record in a table can be associated with one or more records in another table. For example, **each customer can have many sales orders**. In this example the primary key field in the Customers table, Customer ID, is designed to contain unique values.

**Linear equations can be used to represent the relationship between two variables, most commonly x and y**. To form the simplest linear relationship, we can make our two variables equal: y = x y=x y=x. By plugging numbers into the equation, we can find some relative values of x and y.

Relations can be displayed as **a table, a mapping or a graph**. In a table the x-values and y-values are listed in separate columns. Each row represents an ordered pair: Displaying a relation as a table.

A relation is just **a relationship between sets of information**. When x and y values are linked in an equation or inequality, they are related; hence, they represent a relation. Not all relations are functions. A function states that given an x, we get one and only one y.

If there is only one output for every input, you have a function. If not, you have a relation. **Relations have more than one output for at least one input**. The following table of values represents data collected by a student in a math class.

**Gynoids** are humanoid robots that are gendered feminine. They appear widely in science fiction film and art. They are also known as female androids, female robots or fembots, although some media have used other terms such as robotess, cyberdoll, "skin-job", or Replicant.

As of the time of writing, it has raised just over $60,000 with 58 days to go, so there's a very good chance the campaign will be a success. A Little Sophia costs **between $99 and $149**, depending on when it's ordered, and Hanson expects to deliver the bots in December 2019.

around $200 to $1,000

The school tests additional technology on a small scale before making a big investment, Hursey said. The robots cost **about $6,000 each to buy, plus another $1,100 in yearly upkeep**, she said. That's why they started with one robot in one school to see how it worked before buying one for each school.

As simple as a robot. The fact that software robots do not need to be physically manufactured makes their development relatively simple and fast. Creating a new robot from scratch takes approximately **one and a half to four months**. Payback time can be as short as six months.

Taking into account the average power consumption for this size robot of 7.35 kW and the average energy cost of 10 cents per kWh (based on 2013 rates for industrial usage, source: U.S. Department of Energy), he calculates the average cost to operate a medium-sized robot at **75 cents an hour**.

More recently, a Hong Kong-based company developed Sophia, the first anthropomorphic robot capable of displaying **more than 60 different emotions** (Faraj et al., 2020).

So, to answer the big question: **yes, Sophia did die, though not forever**. In the search for answers about her death, I've found even more questions about her existence. To understand why is Sophia so special and why many think she is a scam, we'll start at the beginning.

The app, which will go live this month, will cost $20. Connect it to the Real Doll and you've got a robotic girlfriend in a lifelike form. The total cost is **around $15,000**.
