17<br> If x-2 is a factor of x- bx + b, where b is a<br> constant, what is the value of b ?

aliya0001 [1]

Answer: $b=4$

Step-by-step explanation:

<h3> The complete exercise is: "<em>If $x-2$ is a factor of $x^2 - bx + b$ , where b is a constant, what is the value of b?</em>"</h3><h3 />

You know that a factor of the given polynomial $x^2 - bx + b$ is:

$x-2$

Then, in order to find the value of "b", which is a constant of the polynomial, you need to follow these steps:

1. You must rewrite the polynomial as:

$P(x)=x^2 - bx + b$

2. Now you must substitute $x=2$ into the polynomial:

$P(2)=(2)^2- b(2)+ b$

3. Since 2 is a zero of the polynomial, you can substitute $P(2)=0$ :

$0=(2)^2- b(2)+ b$

4. Finally, you must solve for the constant "b" to find its value. Then, this is:

$0=(2)^2- b(2)+ b\\\\0=4-2b+b\\\\-4=-b\\\\b=4$

PLEASE PLEASE HELP!!!!!<br><br> 1. What is the domain of the function shown below?

<h3>Answer: Choice A</h3>

$-8 \le x < 3 \text{ and } 4 \le x < 8$

=======================================================

Explanation:

Place your pencil on the curve. Then draw a straight vertical line either up or down until you reach the x axis. If you were to start at the left endpoint, and work your way to the right, you'll eventually shade the interval $-8 \le x < 3 \text{ and } 4 \le x < 8$ along the x axis.

We have two separate intervals being shaded in. There's a small gap from 3 to 4 that isn't shaded in.

Refer to the diagram below.
