Sections Of A Graph

The graph of a function of two variables can be better understood by looking at slices or cross sections of the graph parallel to the or planes.

Sections of a graph. Let s define the various parts of a line graph. The line along the bottom is called the horizontal or x axis and the line up the side is called the vertical or y axis. The graph of the function is the set of all points latex left x y right latex in the plane that satisfies the equation latex y f left x right latex.

This is basically a number line and if you ve used number lines before it should look very. And for a hyperbola it is. You read it from the bottom left of the graph.

You plot an ordered pair on graph quadrants. Each of these line graphs shows a change in data over time. Each of the four sections has a specific combination of negative and positive values for x and y.

Each of the resultant sections is called a quadrant. The graph below will be used to help us define the parts of a line graph. If the function is defined for only a few input values then the graph of the function is only a few points.

The special case of a circle where radius a b. X 2 a 2 y 2 b 2 1. The 4 main types of graphs are a bar graph or bar chart line graph pie chart and diagram.

When placed like this on an x y graph the equation for an ellipse is. Slicing is equivalent to holding or constant at and looking at the graph of the resulting single variable function or respectively. In this case the height or length of the bar indicates the measured value or frequency.
