Front

What does it mean for a function to be defined?

Back

A function is defined by a set of ordered pairs where each input (x-value) corresponds to exactly one output (y-value).

Front

What is the difference between domain and range in a function?

Back

Domain refers to all possible input values (x-values) of a function, while range refers to all possible output values (y-values).

Front

How do you find the value of a function at a specific point?

Back

Substitute the specific x-value into the function's equation to find the corresponding y-value.

Front

What is the process of simplifying an algebraic expression?

Back

Combine like terms and apply the distributive property to reduce the expression to its simplest form.

Front

What is a linear function?

Back

A linear function is a function that graphs to a straight line and can be expressed in the form f(x) = mx + b, where m is the slope and b is the y-intercept.

Front

What is the slope-intercept form of a linear equation?

Back

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.
