Miss Smith's math tutorial covers piecewise functions, explaining how to graph, evaluate, and write them. The video begins with an introduction to piecewise functions, followed by a detailed guide on graphing them using T-charts and graphing calculators. It then demonstrates how to evaluate piecewise functions using both equations and graphs. Finally, the tutorial explains how to write piecewise functions from given graphs, emphasizing the importance of understanding slopes, intercepts, and restrictions.

What is a piecewise function?

• A function that is continuous and differentiable everywhere.

• A function that is always linear.

• A function that is defined by multiple sub-functions, each applying to a certain interval of the main function's domain.

• A function that only has one equation.

What does the equation y = 2 represent in the context of piecewise functions?

• A vertical line at x = 2

• A diagonal line with a slope of 2

• A parabolic curve

• A horizontal line at y = 2

How do you determine if a point is included in a piecewise function?

• By checking if the inequality symbol includes an 'or equal to' line

• By looking at the color of the point

• By checking if the point is at the origin

• By seeing if the point is on the x-axis
