Question

Which of the following statements best describes the effect of replacing the graph of y = f(x) with the graph of y = f(x) − 9?

A) The graph of y = f(x) will shift up 9 units.

B) The graph of y = f(x) will shift down 9 units.

C) The graph of y = f(x) will shift left 9 units.

D) The graph of y = f(x) will shift right 9 units.

Answer 1

Down 9 units

Explanation:

Answer 2

we know that

The rule of the translation in this problem is equal to

`(x,y)------> (x,y-9)`

That means

The translation is
`9` units down

therefore

the answer is the option B

The graph of y = f(x) will shift down
`9` units.
