### What is the output variable of a function?

It is a value in the co-domain [range] of the function.

### A function is a rule that assigns each value of the variable to exactly one value of the dependent variable?

I found two answers for this question. A function is a rule that assigns to each value of one variable (called the independent variable) exactly one value of another variable (called the dependent variable.) A function is a rule that assigns to each input value a unique output value.

### What is a dependent quantity?

the output of a function; a variable whose value depends on the value of the input.

### When can we say that a function is a relation?

When it doesn't fulfill the requirements of a function. A function must have EXACTLY ONE value of one of the variables (the "dependent variable") for every value of the other variable or variables (the "independent variable").

### When can we say that a relation is a function?

When it doesn't fulfill the requirements of a function. A function must have EXACTLY ONE value of one of the variables (the "dependent variable") for every value of the other variable or variables (the "independent variable").

false

### How do you know whether a relation is a function?

Use the definition of a function. If, for any value of one variable, there is only a single possible value of the second variable, then the second variable is a function of the first variable. The second variable is often called the "dependent variable". If you can solve an equation explicitly for the dependent variable, then it is a function. If you can NOT solve it for a variable, it may or may not be a function - it turns out that some equations are hard or impossible to solve explicitly for one of the variables.

### What rule assigns each value of the independent variable to exactly one value of the dependent variable?

It is any invertible function.

### What is independent a dependent variables?

The independent variable is the variable that is altered by the scientist, and the dependent variable's value is dependent on the value of the independent variable.

### What is the output of a function a variable whose value depends on the input or independent variable?

the output variable is called the dependent variable. For example the function y = f(x) = 3x here x is independent and y is dependent; y changes when you change x

### A is a rule that assigns each value of the independent variable to exactly one value of the dependent variable?

This will be a math function. Each choice is only going to have one answer in this kind of function.

True
