If a function is translated 6 units down, what is the new equation?

• f(x - 6)

• f(x) - 6

• f(x) + 6

• f(x + 6)

What happens to the graph of a function when it is translated 2 units to the right?

• It moves 2 units up

• It moves 2 units down

How is a function affected by a vertical reflection?

• It is reflected over the y-axis

• It is shifted down

• It is shifted up
