Understanding Transformations of Parent Functions

Mario's math tutorial covers transformations of parent functions, including shifts, stretches, compressions, and reflections. The video explains how to recognize basic graphs and apply transformations using order of operations. It emphasizes understanding the effects of transformations on graphs and provides examples to illustrate these concepts. The tutorial concludes with a summary of key points and encourages viewers to explore more videos on Mario's Math Tutoring channel.

Which of the following functions is represented by a V-shape graph?

• Greatest integer function

• Reciprocal function

• Absolute value function

• Square root function

What effect does subtracting 2 from the x-value in a function have on its graph?

• Shifts the graph left by 2 units

• Stretches the graph vertically

• Compresses the graph horizontally

• Shifts the graph right by 2 units

If a function is multiplied by 2, what transformation occurs?

• Horizontal shift

• Vertical shift

• Horizontal compression

• Vertical stretch

What happens to a graph when it is multiplied by -1?

• It shifts down

• It reflects over the y-axis

• It shifts up

• It reflects over the x-axis

How does grouping a number with x affect the graph of a function?

• It affects the y-direction

• It only stretches the graph

• It affects the x-direction

• It has no effect

What is the result of a horizontal compression on a graph?

• The graph becomes wider

• The graph becomes narrower

• The graph shifts up

• The graph shifts down

In the transformation y = 3√(x + 2) - 1, what is the first step according to the order of operations?

• Shift down by 1

• Shift left by 2

• Vertical stretch by 3

• Reflect over the x-axis

What is the effect of adding a number outside the function on the graph?

• Shifts the graph horizontally

• Shifts the graph vertically

• Stretches the graph horizontally

• Compresses the graph vertically

What transformation occurs when a negative sign is placed in front of a function?

• Reflects over the x-axis

• Shifts the graph up

• Shifts the graph down

• Reflects over the y-axis

How does a negative sign grouped with x affect the graph?

• Shifts the graph right

• Shifts the graph left

• Reflects over the y-axis

• Reflects over the x-axis
