Refer to the above figure.

Which of the following functions is graphed?

Possible Answers:

The correct answer is not given among the other responses.

Correct answer:

Explanation:

Below is the graph of :

Axes_1

The given graph is the graph of  shifted 6 units left (that is,  unit right) and 3 units up. 

The function graphed is therefore

 where . That is,

Example Question #2 : Coordinate Geometry

Axes_1

Refer to the above figure.

Which of the following functions is graphed?

Possible Answers:

Correct answer:

Explanation:

Below is the graph of :

Axes_1

If the graph of  is translated by shifting each point  to the point , the graph of

 

is formed. If the graph is then shifted upward by three units, the new graph is

Since the starting graph was , the final graph is

, or,
