What is the definition of a domain in a relation?

Back

The domain of a relation is the set of all possible input values (x-values) for which the relation is defined.

Front

What is the definition of a range in a relation?

Back

The range of a relation is the set of all possible output values (y-values) that result from the input values in the domain.

How do you find the x-intercept of a linear equation?

Back

To find the x-intercept, set y = 0 in the equation and solve for x.

Front

What are the characteristics of a function?

Back

A function must have exactly one output for each input, meaning no x-value can map to more than one y-value.

What is the significance of intercepts in graphing a linear equation?

Back

Intercepts are the points where the graph crosses the axes, providing key information about the graph's position.
