Question

A function defined by two or more equations over a specified domain is called?

Answer 1

Is called a piecewise function.A function defined by two or more equations over a specified domain is called piecewise function!

Answer 2

A function defined by two or more equations over a specified domain is called a: piecewise-defined function.

A function can be defined as a mathematical expression (equation) that defines or represent the relationship between two or more variable.

Basically, one of the variable is referred to as an independent variable while the other is referred to as a dependent variable.

Additionally, a function associates each variable of the first set exactly with one variable in the other set.

In Science, the different types of functions include the following;

• Periodic function.

• Inverse function.

• Modulus function.

• Signum function.

• Piece-wise defined function.

A piecewise-defined function refers to a type of function that is defined or denoted by two (2) or more mathematical equations over a specific domain.

For example:

$F(x) = \left \{ {{x^3\; - \;2} \atop {x \;+ \;2}} \right.$
