Question

medal
The graph of the function B is shown below. Find B(2).

Answer 1

1?
0

Answer 2

Assuming unit intervals:
$$
\begin{matrix}
x&B(x) \\
-1 &1 \\
0 &3 \\
1 &2 \\
2 &-1 \\
3 &0 \\
\end{matrix}
$$
Can you now find B(2)?

Answer 3

no

Answer 4

Look for the row where x=2, what is B(x) ?

Answer 5

$$
\begin{matrix}
x&B(x) \\
-1 &1 \\
0 &3 \\
1 &2 \\
\large\color{red}2 &\large{\color{red}{-1}} \\
3 &0 \\
\end{matrix}
$$

Answer 6

Does this help?

Answer 7

B(x) when x=2 is -1. Do you see that?
