Question

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

Answer 1

Answer: x=2

Explanation:

1. By definitiion, the independient values of the function are plotted on the x-axis and the dependent values of the function are plotted on the y-axis.

2. Then, keeping this on mind , if B(x)=-1 is plotted along the negative direction of the y-axis, then the independent value is 2. Then, the point obtained is (2,-1).

3. Therefore, the answer is: x=2

Answer 2

So x=2

Explanation:

If B(x) = -1

That means the y value is -1

We need to find on the graph where y =-1

Y= -1 where x =2

So x=2
