Now that you can identify the type of graph, can you determine the value of n in the general equation:

It can be -2,-1, 1, 2 or 3. Then, can you determine if k is negative or positive. You may need to reference Worksheet 5940.

• 1.

### Identify the graph above from your worksheet, and determine if k is negative or positive, and also the value for n (1, 2, 3, -1 or -1). Select TWO options.

• A.

K is positive

• B.

K is negative

• C.

N=1

• D.

N=2

• E.

N=3

• F.

N=-1

• G.

N=-2

A. K is positive
C. N=1
Explanation
Based on the given graph, we can determine that k is positive because the graph is increasing from left to right. Additionally, the graph intersects the y-axis at n=1, indicating that n=1 is the correct value.
