2.2.1 * Linear Functions

... • With functions, we won’t always use the expression y = …. or x = … • Remember, could have multiple letters; must be able to determine what the actual variable is • Function notation does 2 things – 1) Gives a name to the function (typically a single letter) – 2) Tells us what the actual variable i ...

... The algebra shows you how to go directly to the final number. This is an example of finding a function of a function. When you find a function of a function, you are forming a composition of functions. If f(x) is one function and g(x) is another function, you can write g(f(x)) to indicate the value ...
