Question

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

A. -1
B. 1
C. 2

Answer 1

The answer is c, 2.To find this, look on the graph for a point with the y value of -1. (2,-1) is the solution.

Answer 2

C. 2

Explanation:

Here in B(x) = -1

-1 is the value of y

Thus, the only coordinate where y = -1 from the marked points in the graph is: (2, -1).

Hence, the value of x in B(x) = -1 is 2

Thus, the only correct option is (C).
