Obtaining Equations from Piecewise Function Graphs You may be asked to write a piecewise function, given a graph. To review how to obtain equations from linear graphs, see Obtaining the Equations of a Line, and from quadratics, see Finding a Quadratic Equation from Points or a Graph.

However, not all these equations are functions. In math, a function is an equation with only one output for each input. In the case of a circle, one input can give you two outputs - one on each side of the circle.

Thus, the equation for a circle is not a function and you cannot write it in function form. Apply the vertical line test to determine if your equation is a function. If you can move a vertical line along the x-axis and only intersect one y at a time, your equation is a function as it follows the only one output for each input rule.

Solve your equation for y. Sciencing Video Vault Decide on a name for your function. Most functions use a one-letter name such as f, g or h.

Determine what variable your function depends upon. The left side of your function is the name of your function followed by the dependent variable in parenthesis, f x for the example. Tip You write functions with the function name followed by the dependent variable, such as f xg x or even h t if the function is dependent upon time.

You read the function f x as "f of x" and h t as "h of t". Functions do not have to be linear. The equation is nonlinear because of the square of x, but it is still a function because there is only one answer for every x.

When evaluating a function for a specific value, you place the value in the parenthesis rather than the variable. Warning Do not confuse function names with multiplication.

Function f x is not variable f times variable x. Function f x is a function named f that depends upon x.Building up the equation symbolically is different than building it up in a string. When doing it symbolically you can create the template and then subs() the values and variable names in to make it more specific.

The write() method writes HTML expressions or JavaScript code to a document. The write() method is mostly used for testing: If it is used after an HTML document is fully loaded, it will delete all existing HTML. Note: When this method is not used for testing, it is often used to write some text to. Pearson Prentice Hall and our other respected imprints provide educational materials, technologies, assessments and related services across the secondary curriculum. Write the input and output of a function as an "ordered pair", such as (4,16). They are called ordered pairs because the input always comes first, .

I want to write a query like this: SELECT metin2sell.comd, MAX(metin2sell.comatedPrice, metin2sell.comtedPrice) FROM Order o But this isn't how the MAX function works, right?

It is an aggregate function so it expects a single parameter and then returns the MAX of all rows.
