Graph transformations

What is a stretch with a fractional scale factor?

• A transformation that rotates the graph
• A transformation that shifts the graph horizontally or vertically
• A transformation that shrinks or contracts the graph along the x-axis or y-axis
• A transformation that reflects the graph over the x-axis or y-axis

What is the effect of a vertical stretch on a graph?

• It compresses the graph horizontally
• It expands the graph vertically
• It compresses the graph vertically
• It expands the graph horizontally

What is an example of a vertical translation in a graph of a function?

• -f(x)
• f(x) + c
• f(-x)
• f(x + c)

What are the different types of transformations of graphs?

• Translations, rotations and stretches
• Translations, rotations, dilations, and compressions
• Translations, rotations, dilations, and reflections
• Translations, reflections and stretches

What is a horizontal translation?

• A transformation that moves a graph up or down
• A transformation that stretches or compresses a graph horizontally
• A transformation that moves a graph left or right
• A transformation that stretches or compresses a graph vertically

What is the difference between a reflection and a stretch/compression of a graph?

• A reflection and a stretch/compression are the same thing
• A reflection changes the size of the graph, while a stretch/compression flips the graph across an axis
• A reflection flips a graph across an axis, while a stretch/compression changes the size of the graph
• A reflection and a stretch/compression have no effect on a graph

How do you reflect a graph across the x-axis?

• Replace z with -z in the equation of the function
• Replace y with -y in the equation of the function
• Replace x with -x in the equation of the function
• Replace w with -w in the equation of the function

What is the effect of a horizontal translation on a graph of a function?

• Shifts the graph up or down
• Shifts the graph left or right

Which of the following is an example of a reflection across the y-axis?

• f(x) + 2
• h(x) = f(-x)
• f(x - 2)
• g(x) = -f(x)
