|x - 3| = -6/-3
Two negatives = a positive so make it |x - 3| = -6/-3
|x - 3| = 2
In order to find the answers we need to break it down into these two problems
x - 3 = 2 and -(x - 3) = 2
For the first one its 5 since 5 - 3 = 2 and 2 + 3 = 5
For the second one its 1
Now we're done lets just collect both answers

Remember, for |a|=b, assume and solve a=b and a=-b

so

first get into |a|=b form

-3|x-3|=-6
divide both sides by -3
|x-3|=2
so solve
x-3=2 and x-3=-2
add 3 to both sides
x=5 and x=1

the solutionsa re x=1 and 5

Find a quadratic model for the set of values: (-2, -20), (0, -4), (4, -20). Show your work.

Ok... so this question can be solved by using simultaneous equations.

Use the general from of a parabola

$y = ax^2 + bx + c$

you know the value of c, the y-intercept... y = -4

which means the equation is

$y = ax^2 + bx - 4$

now use the other 2 points to get 2 equations in 2 unknowns

(-2, -20) just substitute

$-20 = (-2)^2a + (-2)b - 4 ~~~or~~~ -20 = 4a - 2b - 4$

this becomes

$4a - 2b = -16$

now the other equation using (4, -20)

The simplified form is

The set of ordered pairs represents a

Murrr4er [49]

Answer:

The rule that represents the function is $y=x^2+1$ therefore the function is $f(x)=x^2+1$

Step-by-step explanation:

We have 5 ordered pairs in the plane xy. This means that every pair has the form (x, y).

Then, we have 5 values of x, which will give us 5 values of y, using the rule that represents the function.

The easy evaluation is that when x=0, the value of y is y=1, and then we can evaluate the rule for x=-1, and x=1, the value of y is the same, y=2. We can see here that we have a parabolic function, that is not centered in the origin of coordinates because when x=0, y=1.

So we propose the rule $y=x^2+1$ which is correct for the first 3 values of x.

Now, we evaluate the proposed rule when x=2, and when x=3. This evaluations can be written as

$f(2)=2^2+1=5$
