Find a quadratic model for the set of values: (-2, -20), (0, -4), (4,-20) Show your work
Usimov [2.4K]
A quadratic function:
y=ax^2+bx+c

First, take the point (0,-4) and plug the values (x,y) into the equation:
-4=a \times 0^2+b \times 0 +c \\&#10;-4=c

So the equation is y=ax^2+bx-4.

Now plug the values of the other two points into the equation and set up a system of equation:
-20=a \times (-2)^2+b \times (-2)-4 \\&#10;-20=a \times 4^2+b \times 4-4 \\ \\&#10;-20+4=4a-2b \\&#10;-20+4=16a+4b \\ \\&#10;-16=4a-2b \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ | \div 2 \\&#10;-16=16a+4b \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ |\div 4 \\ \\&#10;-8=2a-b \\&#10;\underline{-4=4a+b} \\&#10;-12=6a \\&#10;\frac{-12}{6}=a \\&#10;a=-2 \\ \\&#10;-8=2a-b \\&#10;-8=2 \times (-2)-b \\&#10;-8=-4-b \\&#10;-8+4=-b \\&#10;-4=-b \\&#10;b=4

The function is:
\boxed{y=-2x^2+4x-4}

Is (0,0) a solution to this system y&gt; x2+x-4 y &lt;x2+2x+1
Aliun [14]

Answer:

Yes, the ordered pair (0,0) is a solution of the system

Step-by-step explanation:

we have

y\geq x^{2}+x-4 ----> inequality A

y < x^{2} +2x+1 ----> inequality B

we know that

If a ordered pair is a solution of the system of inequalities, then the ordered pair must satisfy both inequalities

<u>Verify</u>

For x=0,y=0

<em>Inequality A</em>

0\geq (0)^{2}+0-4

0\geq -4 ----> is true

so

The ordered pair satisfy inequality A

<em>Inequality B</em>

0 < (0)^{2} +2(0)+1

0 < 1  ----> is true

so

The ordered pair satisfy inequality B

therefore

The ordered pair (0,0) is a solution of the system
