I. Linear Functions (p.214)

A function f is a linear function if ________________________ for real numbers a and b.

a ≠ , then the domain and the range of the linear function are both ________________.

If a = 0, then the equation becomes the constant function, _______________. In this case, the

domain is ___________ and the range is ___________.

II. Graphing a Linear Function (pp.214 – 216)

A. Graphing using the intercepts:

Recall: The x-intercept is _____________________________________________________ and

is the point ( 0, #).

Ex. Graph f(x) = -2x + 4 . Label each intercept. State the domain and range.

B. Graphing a constant function:

Ex. Graph f(x) = 2. Label any intercepts. State the domain and range.

This graph is a _____________________line and is a function.

C. Graphing x = a:

Ex. x = – 3 . Label any intercepts. State the domain and range.

This graph is a _____________________ line and is not a function. (Why?)
