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.

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.
