RELATIONS

We learned about relations and finding domains and ranges.

Let’s start with the coordinate plane.

Coordinate planes are divided into four quadrants, which are labeled quadrant 1, quadrant 2, quadrant 3, and quadrant 4 in roman numerals.

Quadrant 1 is located on the top right corner, quadrant 2 on the top left corner, quadrant 3 on the bottom left corner, and quadrant 4 on the bottom right corner.

The point where the x-axis and the y-axis meets is the origin. The origin is on the center of the coordinate plane, and its x-coordinate and y-coordinate are the same as in zero. -> (0,0)

Next, we have discreet and continuous variables.

You can leave the points of  the discreet variables as they are, but you have to connect the points of the continuous variables.

There are five ways to show relations.

You can use a T chart, an equation, ordered pairs, a graph, or a mapping diagram.

Lastly, we have domains and ranges.

The domain has to do with the values of x, and the range has to do with the values of y.

I will post more next week.
