Example 1:y=2x+4In this case, the independent variable is x, so one way to write this in function notation would bef(x)=2x+4. Function notation can also be used for formulas. Example 2: The perimeter of a square would be given by the formulaP=4s, where s is the length of one ...
In math, a function is defined as an expression that describes the relationship between an independent variable (input) and a dependent variable (output) in which only one output exists for every input. Functions are applicable in everyday life and many professions. For example, the distance a...
Example 2: Determining If Class Grade Rules Are Functions In a particular math class, the overall percent grade corresponds to a grade point average. Is grade point average a function of the percent grade? Is the percent grade a function of the grade point average? The table below shows a ...

Not all equations or relations are functions. For example, the equation y2=xy^2 = xy2=x is not a function for dependent variable y. Re-writing the equation it becomes y=xy = \sqrt{x}y=x or, in function notation, y = f(x) and f(x...
MathHelp.com Function Notation These "y=" equations arefunctions. But the question you are facing at the moment is "Why do I need this function notation, especially when I've got perfectly nice 'y=', and how does this notation work?" ...
Worksheet on this topic How do you evaluate functions? The same way that you substitute values into equations! Example 1 What is the value ofxgiven the equationy=2xwhenx=5? Substitute '5' in for x : The one new aspect of function notation is theemphasis on input and output. ...
Don't let the notation for this topic worry you; it means nothing more than exactly what it says: add, subtract, multiply, or divide; then simplify and evaluate as necessary. Don't overthink this. It really is this simple.Oh, and that last example? They put that in there so you can...

To see what this looks like, let's start with thefunction notationfor the basic quadratic: f (x) =x2 A function transformation takes whatever is the basic functionf (x)and then "transforms" it (or "translates" it), which is a fancy way of saying that you change the formula a ...
