It is a function because it passes the vetical line test

It is NOT a one-to-one function because it does not pass the horizontal line test.

The parabola with equation y=ax^2+bx+c is graphed with a point of (4,12) and a vertex of (2, -4). The zeros of the quadratic ax^2 + bx + c are at x=m and x=n, where m>n. What is m-n? 

You get some nice curves with x = cos(a) + cos(b); y = sin(a) + sin(b).  

Presumably, with an infinite number of points the area covered is that of a circle with radius 2.

Area = 4pi.

The answer Geno gave is almost right; he just made a small error in the final step:

Geno's answer:

   3x² + 12x + 4

=  3(x² + 4x) + 4

=  3(x² + 4x + 4) + 4 - 12

=  3(x + 2)² - 12     This last line should be 3(x + 2)² - 8   (as 4 - 12 = -8)

so a = 3, h = -2, and k = -8

What is the value of X

See my answer at:  https://web2.0calc.com/questions/what-is-the-polar-form-of-the-equation-of-x-6-2-y-2-36#r2 

"What is the polar form of the equation of (x+6)^2+y^2=36?"

The following shows the steps in the simplification:

11. The soccer ball has 52 faces with 20 pentagons.

m - n = 12 - 5 = 7.

The answer is (-inf,-135].

The rectangular form is y = 3*sqrt(3)*x.

Nevermind, I solved it!

It is very poorly presented. That is what it is.

(guest's  question I mean)

There are 12 digaonals that have a length of P_1 P_2, which from the Sine Law, is sin (15 degrees).  There are 12 diagonals that have a legnth of P_1 P_3, which from the Sine Law, is sin (30 degrees).  We can appy the same reasoning to the other diagonals, which gives us a total sum of

(12 sin 15)^2 + (12 sin 30)^2 + (12 sin 45)^2 + (12 sin 60)^2 + (12 sin 75)^2 + (12 sin 90)^2 + (12 sin 105)^2 + (12 sin 120)^2 + (12 sin 135)^2 + (12 sin 150)^2 + (12 sin 175)^2 = 440.

There is no remainder.

\(\frac{n^2}{n}=n\) thus it will give you the positive integer you started with. 

But how...

If you mean \(3100000+170x^3xy\)

then you should get \(3100000+170x^4y\)
