Front

What is the equation of a vertical reflection of the absolute value function?

Back

f(x) = -|x|

Front

What does a horizontal translation of a function do?

Back

It shifts the graph left or right on the x-axis.

Front

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

Back

It makes the graph taller and narrower.

Front

What is the equation of a function that shifts up 2 units?

Back

f(x) = |x| + 2

Front

What does a negative sign in front of an absolute value function indicate?

Back

It reflects the graph across the x-axis.

Front

What is the equation of a function that compresses the absolute value graph?

Back

f(x) = 2|x|

Front

What does a horizontal stretch do to the graph of a function?

Back

It makes the graph wider.

Front

What is the effect of adding a constant to the inside of an absolute value function?

Back

It shifts the graph horizontally.

Front

What is the equation of a function that shifts right 3 units?

Back

f(x) = |x - 3|

Front

What does the term 'vertical translation' mean?

Back

It shifts the graph up or down on the y-axis.
