The video tutorial covers graphing functions, focusing on shifting graphs and understanding domain and range. It explains how subtracting a number inside a function shifts the graph and how to use zoom options for better visualization. The domain is discussed both algebraically and graphically, emphasizing the importance of checking constraints like fractions and square roots. The range is introduced, highlighting how to determine the lowest and highest points on a graph, with a focus on zero inclusion.

What is the effect of subtracting a number inside a function's bracket?

• It shifts the graph to the right.

• It shifts the graph to the left.

• It shifts the graph downwards.

• It shifts the graph upwards.

What should you do if your graph doesn't look correct?

• Change the function.

• Use zoom standard.

• Ignore the graph.

• Recalculate the function.

What is the purpose of using zoom standard in graphing?

• To change the graph's color.

• To add labels to the graph.

• To ensure the graph is displayed correctly.

• To adjust the graph's size.

How can you find the domain of a function algebraically?

• By counting the number of points on the graph.

• By looking for when the function is not defined.

• By checking the graph's color.

• By measuring the graph's height.

What does the domain of a graph represent?

• The color of the graph.

• How far the graph extends left and right.

• The width of the graph.

• The height of the graph.

What is the domain of the graph discussed?

• One to infinity

• Zero to infinity

• Negative infinity to positive infinity

• Negative infinity to zero

What should you check for when finding the domain algebraically?

• Numbers and letters

• Lines and curves

• Colors and shapes

• Fractions and square roots

What is the purpose of visually checking the graph?

• To count the number of points.

• To ensure the graph is colorful.

• To verify the algebraic domain.

• To measure the graph's height.

What is the range of a function?

• The set of all possible input values.

• How low and high the graph goes.

• The color of the graph.

• The distance between two points on the graph.

How is the range of a function represented?

• With a pie chart.

• Using a line graph.

• In interval notation.

• As a list of numbers.
