Front

What is the definition of a linear equation?

Back

A linear equation is an equation that forms a straight line when graphed, typically in the form y = mx + b.

Front

What is a nonlinear equation?

Back

A nonlinear equation is an equation that does not form a straight line when graphed, such as quadratic or exponential equations.

Front

What does the term 'domain' refer to in functions?

Back

The domain of a function is the set of all possible input values (x-values) that the function can accept.

Front

What does the term 'range' refer to in functions?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce.

Front

What is an independent variable?

Back

An independent variable is a variable that represents the input of a function, often denoted as x.

Front

What is a dependent variable?

Back

A dependent variable is a variable that represents the output of a function, often denoted as y.

Front

What is the difference between input and output in a function?

Back

Input refers to the values you put into a function (x-values), while output refers to the values you get out of a function (y-values).

Front

What is a set of ordered pairs?

Back

A set of ordered pairs is a collection of pairs of numbers, typically written as (x, y), where x is the input and y is the output.
