Answer:
C - The relationship represents a function because each input gives one unique output.
Step-by-step explanation:
To see if it is a function we can do the line test where we have a vertical line and "drag" it along the line. As long as it only hits the line once in every situation it is a function! We can see this passes and therefore the answer is c.
(why is it not d? you can have a non-linear line, but still have a function)
The first y equals -3 and the second y equals -9
Yes, you need to make the denominators the same. 2/3 becomes 8/12. So now you add 7/12 and 8/12, getting 15/12. But you're not done you need to simplify 15/12. The answer is 1 1/4.
Given:
The function is:

The graphs of functions
and
.
To find:
The function
.
Solution:
We have,

The function
is vertically compresses to get the graph of the function
. So, the function
is:

...(i)
From the given graph it is clear that the graph of the function
passes through the point (3,3). So, putting
and
in the above function, we get




Putting
in (i), we get
Therefore, the correct option is D.
