Answer:
k(-1) = 7.
Step-by-step explanation:
k(-1) is the value of the function k when x = -1.
You read this off the graph.
Find the value of the point on the graph which corresponds to x = -1. From x = -1 on the horizontal axis move straight up until you meet the graph of k. Now look horizontally to the right and read off the value on the vertical
y-axis
You'll find it is 7.

Given:
The area of a rectangle = 14 square units.
The side lengths are a and b.

To find:
The value of b.
Solution:
We know that, the area of a rectangle is:

The area of the given rectangle is:




On further simplification, we get



Divide both sides by 7.


Therefore, the value of b is 6 units.
