Learn How to Graph a Piece Wise Function

The video tutorial explains how to graph functions, specifically focusing on X + 3 and -2X - 3. It covers graphing these functions separately and as piecewise functions, detailing the steps and considerations for each. The tutorial also discusses the concepts of domain and range, emphasizing how they apply to the given functions.

What is the correct way to graph the function X + 3 for all X values?

• Graph it for all X values from negative to positive infinity

• Graph it only for X values equal to 0

• Graph it only for X values less than -2

• Graph it only for X values greater than 2

When graphing the function X + 3 for X values less than -2, what type of dot is used at the endpoint?

• A filled dot

• A square dot

• An open dot

• A triangle dot

For the function -2X - 3, what is the Y-intercept?

• -3

• 0

• -2

• 3

What is the domain of the function -2X - 3 for X values greater than or equal to -2?

• From 0 to infinity

• From -2 to infinity

• From negative infinity to infinity

• From -2 to 2

What is the range of the function -2X - 3?

• From -3 to infinity

• From negative infinity to 1

• From -3 to 1

• From 0 to 3
