What does it mean to plot something as a function of something?

A function defines one variable in terms of another. The statement “y is a function of x” (denoted y = y(x)) means that y varies according to whatever value x takes on.

How do you write something as a function of something?

To write such function in function notation, we simply replace the variable y with the phrase f(x) to get; f(x) = 3x + 7. This function f(x) = 3x + 7 is read as the value of f at x or as f of x.

How do you determine if something is a function of something else?

Determining whether a relation is a function on a graph is relatively easy by using the vertical line test. If a vertical line crosses the relation on the graph only once in all locations, the relation is a function. However, if a vertical line crosses the relation more than once, the relation is not a function.

What does it mean to have something as a function of something else?

Definition of a function of 1 : something (such as a quality or measurement) that is related to and changes with (something else) Height is a function of age in children. 2 : something that results from (something else) His personal problems are a function of his drinking.

Which graph is used for temperature?

line graph
A line graph is also used when there are two variables—but only makes sense when you’re tracking changes over a continuous measurement (e.g., time, temperature, distance). Line graphs are especially useful for illustrating direction (i.e., peaks and dips) rather than magnitude.

How does a line plot help you understand temperature data?

A line graph is a powerful tool because it shows a relationship between two variables. Here, the line graph shows how the number of frog croaks per minute changes as temperature changes. Line graphs also allow you to identify trends and relationships in the data, and thus infer values you did not actually measure.

What does it mean for something to be a function of something else?

Definition of a function of 1 : something (such as a quality or measurement) that is related to and changes with (something else) Height is a function of age in children. It increases as their age increases. 2 : something that results from (something else) His personal problems are a function of his drinking.

How do you plot something as a function in Excel?

How to Graph a Function in Excel

1. Create the headers for your data table.
2. Enter the first and second interval of your input variable (for example, “x” or “sales”), which you’ll use to plot the function.
3. Type an equal sign “=” into cell B2 and then type your formula directly after it, without leaving a space.
