# Write a math function

We have a new server! Our server has been upgraded and now is amazingly fast.  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.

Functions assign outputs to inputs. The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0. We can also define special functions whose domains are more limited.

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.
