Function, describes a correlation or coincidence between a dependent variable () and an independent variable (). The legitimacy of this relationship between the variables is called the " correspondence rule ".
Function, describes a correlation or coincidence between a dependent variable () and an independent variable (). The legitimacy of this relationship between the variables is called the " correspondence rule ".
The verbal representation of a function expresses the connection between variables verbally, i.e. through a story.
A typical verbal representation of a function can look like this:
A tabular representation of a function is a demonstration of the legitimacy of a function using a table of values (independent variable) and the corresponding values (dependent variable).
In general, a table of values is shown as follows:
Which of the following equations corresponds to the function represented in the graph?
Which of the following equations corresponds to the function represented in the table?
Is the given graph a function?
Is the given graph a function?
Is the given graph a function?
Which of the following equations corresponds to the function represented in the graph?
Use the formula for finding slope:
We take the points:
We substitute the point and slope into the line equation:
We combine like terms:
Therefore, the equation will be:
Which of the following equations corresponds to the function represented in the table?
We will use the formula for finding slope:
Let's take the points:
We'll substitute the point and slope into the line equation:
Let's combine like terms:
Therefore, the equation will be:
