Answer:
"(1.) 2"
Explanation:
Whenever we are given a notation such as:
A(x) = z
We can say that for the value of x, we get a value of z
The x value is the x-coordinate and the z value is the y-coordinate that corresponds to it in the graph.
We are given,
B(x) = -1
So, we can say:
at a certain x value the y-value is -1
Now, we look at y = -1 line and find the point.
This is the "lowest" point on the graph shown that corresponds and falls on y = -1. Now, which x-value does it correspond to??
It corresponds to x = 2, because it is located at 2 units in x-direction and down 1 unit (which is y = -1).
So x value is x = 2
Answer choice 1 is right.
