The video tutorial covers the basics of square roots and graphing, including techniques for plotting graphs with square roots and understanding functions and their transformations. It introduces y-squared functions and their properties, discusses reflections and relations in graphing, and explains circle equations and their graphing.

What is the reason for not drawing a graph over a certain part when dealing with square roots?

• The graph is too complex to draw.

• The graph does not intersect the x-axis.

• The graph is a straight line.

• The square root of a negative number is undefined.

What is the square root of a quarter?

• 2

• 1

• 0.5

• 0.25

How can the square root of x cubed be expressed in index notation?

• x to the power of 0.5

• x to the power of 3

• x to the power of 2

• x to the power of 1.5

What happens when you take the square root of a function and reflect it across the x-axis?

• It becomes a straight line.

• It forms a parabola.

• It flips upside down.

• It remains unchanged.

What is the result of y squared equals a function?

• A parabola

• A relation

• A straight line

• A cubic function

What test does a graph fail if it is a relation and not a function?

• Curved line test

• Vertical line test

• Horizontal line test

• Diagonal line test

What does y squared equals f(x) represent in terms of graphing?

• Only the top half of the graph

• A straight line

• Only the bottom half of the graph

• The entire graph, both top and bottom

What is the shape of the graph when y squared equals x minus two?

• A straight line

• A parabola

• A circle

• A cubic function

What is the difference between y equals the square root of f(x) and y squared equals f(x)?

• One is a function, the other is not.

• One is a relation, the other is not.

• One represents the top half of the graph, the other the whole graph.

• One represents a straight line, the other a curve.

What does the unit circle represent in terms of y squared?

• The entire circle

• A straight line

• Only the bottom half of the circle

• Only the top half of the circle
