ANSWER
The correct answer is option A.
[tex]B(2)= - 1[/tex]
EXPLANATION
Given that [tex]B[/tex]
is a function of [tex]x[/tex],
then we can write the point, [tex](x,y)[/tex] as [tex](x,B(x))[/tex]
[tex]B(2)[/tex] is just the y-value of point that has an x-coordinate of [tex]2[/tex]
From the grid, each of the boxes is 1 unit.
This means that, when we count 2 units to the right, we will get [tex]x = 2[/tex]
If we move down one unit, we get the point with coordinates [tex](2,-1)[/tex]
This means that
[tex]B(2)= - 1[/tex]
