Master Graphing the Reciprocal Function with Labeling Domain and Range

The video tutorial explains how to graph reciprocal functions, identify their domain and range, and apply transformations. It covers the characteristics of reciprocal function graphs, including asymptotes, and discusses the effects of transformations such as stretching, compressing, reflecting, and shifting. Practical examples are provided to illustrate these concepts, and the importance of understanding transformations for accurate graphing is emphasized.

What is the shape of the graph of a basic reciprocal function?

• A circle

• A straight line

• A parabola

• A hyperbola

What happens to the graph of a reciprocal function when it is multiplied by a constant greater than 1?

• It reflects over the x-axis

• It compresses horizontally

• It stretches vertically

• It shifts to the right

How does a horizontal shift affect the domain of a reciprocal function?

• It reflects the domain over the y-axis

• It does not affect the domain

• It changes the range

• It shifts the domain by the same amount

If a reciprocal function is shifted 2 units to the right, what happens to its vertical asymptote?

• It remains unchanged

• It disappears

• It moves 2 units to the left

• It moves 2 units to the right

What is the effect of reflecting a reciprocal function over the x-axis?

• It changes the domain

• It changes the range

• It does not affect the graph

• It reflects the graph over the y-axis as well

What is the domain of a reciprocal function after it is shifted 3 units to the left?

• All real numbers except 0

• All real numbers except 3

• All real numbers

• All real numbers except -3

What is the effect of a negative sign in front of a reciprocal function?

• It shifts the graph up

• It stretches the graph

• It compresses the graph

• It reflects the graph over the x-axis

How does a vertical shift affect the range of a reciprocal function?

• It reflects the range over the x-axis

• It does not affect the range

• It shifts the range by the same amount

• It changes the domain

When a reciprocal function is shifted up by 2 units, what happens to its horizontal asymptote?

• It remains unchanged

• It disappears

• It moves down by 2 units

• It moves up by 2 units

What is the range of a reciprocal function after it is shifted 4 units up?

• All real numbers except 0

• All real numbers except -4

• All real numbers except 4

• All real numbers
