ANSWER
The correct answer is C
EXPLANATION
[tex]B(1)[/tex]
is just the y-value of the point where
[tex]x = 1[/tex]
That is, the image of 1.
If we were given the function
[tex]B(x)[/tex]
,we would have plug in 1 to find
[tex]B(1).[/tex]
Since the function is not given, we were given the graph so that we trace
[tex]B(1)[/tex]
from it.
So we read from the grid to find that y-value .
Each grid is one unit. So moving one unit on the x-axis and two units on the y-axis will give us the point
[tex](1,2)[/tex]
This means that,
[tex]B(1) = 2[/tex]
