| Weekly Trivia Question #4
1. There is a function (for example, f(x) = x), that will, when graphed, give an x and y axis (A vertical plus sign +) , intersecting at a point (p,q). Find the general form of this function. (In simplest form)
2. Who is responsible for my signature quote? ("Common sense is not so common")
3. What is the heat given off by black holes called?
4. When was the White House burned down? (<---easy one)
If I owe you rep points, tell me. Sorry there's only 4 this week.
Good luck.  |

Good luck. | would that be the x-ray emissions. | |

| No, specifically. And I beleive that there's more than X-rays, anyway, but I'm not positive. | |

| ah well if you won't give me x-rays I'll take 1812 as the burning down of the white house
Sorry war of 1812 but burnt down in 1814

| You've got to clarify the math question; it doesn't quite make sense. Do you mean two lines parallel to the axes, and intersecting at (p,q)? | |

| yes, two lines with one function.
Sorry, I realize that it was unclear. | |

| Number one is a trick question. Part of deciding if something is a function is called the "vertical line test", which this by definition fails. | |

| Ignore the vertical line test.
This isn't a "function", but express it as such.
And it breaks another rule of math, but you'll have to figure that out. | |

| Voltaire, and if soldier is wrong, y=mx+b. Also, black holes expel turbulent friction, which is picked up on x-rays and UV Rays

| Voltaire is indeed correct.
f(x) = px + q, which is what I assume you meant, isn't.  | |

| Hawking radiation it is.
It's a single function, not piecewise. | |

However, is it parametric? | |

| I can't remember that term, what's parametric? | |

| oh, yes.
No, it is not. It can be expressed as f(x) = ... | |

| I didn't pay attention the 1st time. f(x)=x shows the Inverse property of multiplication, therefore, it is an inverse function. | |

| Unless it's an identical function. I always got those two mixed up. | |
