How piecewise functions work
Enter each expression using x, such as x^2, 2*x+1, or sqrt(x).
Use conditions like x<0, x>=0, or x>1 && x<=5.
The calculator uses the first condition that is true for your chosen x-value.
Frequently asked questions
What is a piecewise function?
A piecewise function uses different formulas for different portions of its domain.
Does the order of pieces matter?
Yes. If conditions overlap, the calculator uses the first matching piece from the top.
Can the function be undefined?
Yes. If none of your conditions match the selected x-value, the result is shown as undefined.
