Question

The graph of the function B is shown below. If B(x) = -1, then what is x?

Answer 1

x = 2, that is B(2) = - 1

From the coordinate diagram, the value of x ( x- axis ) corresponding to the value of y = -1 ( y- axis ) is x = 2

That is the point (2, - 1 )

Answer 2

Answer:  The required value of x is 2.

Step-by-step explanation:  We are given the graph of the function B(x) as shown in the figure.

We are to find the value of x such that B(x) = -1.

From the graph, we note that some points are plotted satisfying the function B(x) as follows :

(x, y= (-1, 1),  (1, 2),  (2, -1)  and  (3, 0), where  y = B(x).

So, if y = B(x) = -1, then the corresponding value of x is 2.

Thus, the required value of x is 2.
