The third graph represents a function.
In a function, every input (x value) has <em>exactly</em> one output (y value). If even a single input has zero or two outputs, the graph does not represent a function.
A good way of testing this is using a vertical line. As you move a vertical line from left to right across a graph, it should always be touching exactly one point on the graphed line.
In this case, every graph fails this vertical line test except for the third graph, so the third graph represents a function.

Answer:
Step-by-step explanation:
<u>You need to find the difference:</u>
- 17.50x + 25 - (8.50x + 3) =
- 17.50x - 8.50x + 25 - 3 =
- 9x + 22
Correct one is B
Answer:
B) 
Step-by-step explanation:
1. First, we have to know that two negatives equal positive.
2. Given the information above, 
can simplify to 
.
3. Let's go through each answer choice and see which one also simplifies to .
A:
B:
Therefore, the answer is B) .
The first step of solving this problem is to find your x, which is the unknown number. The unknown number is the age of Max. Once you find the x you can write out your equation.
The equation for this problem is:
2x+8=26
the first step is to subtract 8 from both sides so that all you have on the left side is 2x and your equation will look like ths:
2x=18
after subtracting the 8; divide everything by the coefficient of x which is 2, your result is:
x=9
Max is 9 years old.
