Answer:
-1
Step-by-step explanation:
A function is represented by the following symbol f(x) where f(x) further represents y like this ,

so in this question they are asking what is f(5) which means when the value of x is 5 what is the value of y?
We can see in the graph when x = 5 the value of y is -1 to be exact so
f(5) = -1
or

I'm pretty sure that would go down into the negatives.
The answer will be narrow
Step-by-step explanation:
- 8-2x<u><</u><u> </u><u>5</u>
- -2x<u><</u>5-8
- x<u><</u><u> </u>-3/-2
- x<u><</u>1.5
hope it helps.
The answer would be D, 12 units! :)
