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

(1.) 2
(2.) 1
(3.) -1

"(1.) 2"

Step-by-step 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.

(1.) 2

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
