A graph is used for graphing lines and points. A graph consist of rows columns and units.
Unless otherwise specified, they are simply called 'units'.
To shift a funcion (or its graph) down "a" units, you subtract "a" from the function. For example, x squared gives you a certain graph; "x squared minus a" will give you the same graph, but shifted down "a" units. Similarly, you can shift a graph upwards "a" units, by adding "a" to the function.
it's to help you with your counting
It is a scale.
The main difference is that the vertical scale for a frequency graph is in units (or numbers) whereas in a percentage graph, it is in percentages,
The units are velocity / time, or acceleration. In SI units, that would be meters/second2.
The graph of is shifted 3 units down and 2 units right. Which equation represents the new graph?
The second graph is shifted upwards by 4 units.
