Answer:
No
Step-by-step explanation:
By the Factor theorem
If (x - h) is a factor of f(x) then f(h) = 0
Here (x - 2) with h = 2 and f(x) = 4 + 5
+ 1 , then
f(2) = 4 + 5
+ 1
= 4(32) + 5(16) + 1
= 128 + 80 + 1
= 209
Since f(2) ≠ 0 then ( x - 2) is not a factor
The second one doesn't represent a function, because for some values of "x", you get two different values for "y" (which should not happen, if that were a function).
In every function, you must have a single "y" value for each "x" in the domain.
__________
In order to see it better, you can trace a vertical line onto that graph.
If that line and the graph intersects in more than one point, then that graph doesn't represent a funcion.
Look into the attached picture and see. That vertical red line and the graph intersects in two distinct points. Therefore, it can't represent a function.
Any doubt? Please, comment below.

Answer:
<u>The correct answer is 15 1/2 inches</u>
Correct graph:
Adding it below from previous question that can be found at brainly
Step-by-step explanation:
As we can see in the line plot below, we have:
- 3 * 1/2 = 1.5
- 5 * 1 = 5
- 6 * 1 1/2 = 9
Now, adding up we have:
1.5 + 5 + 9 = 15.5 or 15 1/2 inches
