Graphs Tell a StoryWhat story does this graph tell?


W hat story does this graph tell without labels and units it is difficult to know the story

What story does this graph tell? – Without Labels and units, it is difficult to know the story….

Water Depth

Your turn
Your turn…..

  • Draw a graph of an event, and describe the event with words (write a story).

  • Include labels, units, and a title with your graph.


Shapes of graphs
Shapes of graphs.

  • In nature, there are only a few basic graph shapes that describe many phenomenon such as gravity, light intensities, growth and decay rates, etc.

  • In this class, we will focus on four of these shapes of graphs.

  • In science, the objective of a graph is often to describe the relationship between the independent and dependent variables.

  • The relation between variables can be stated as an equation… The equation of the graphed line.



The linear graph
The simple shapes we will soon see, the graph can usually be made into a line by raising the independent variable ( the x-axis) to a power.Linear Graph


The graph of a square or graph of the independent variable raised to a power
The Graph of a simple shapes we will soon see, the graph can usually be made into a line by raising the independent variable ( the x-axis) to a power.SquareOr graph of the independent variable raised to a power.


The graph of a square root
The Graph of a simple shapes we will soon see, the graph can usually be made into a line by raising the independent variable ( the x-axis) to a power.Square Root


The graph of an inverse relation or graph of the independent x axis raised to the 1 power
The Graph of an simple shapes we will soon see, the graph can usually be made into a line by raising the independent variable ( the x-axis) to a power.Inverse relationOr graph of the independent x-axis raised to the -1 power.


Determine the relation which the given data describes
Determine the relation which the given data describes. simple shapes we will soon see, the graph can usually be made into a line by raising the independent variable ( the x-axis) to a power.
