What
+SWAT model inverse variation
graphically
How
Graphing calculators
|
A fraction that has a denominator
of 0 has no value; it is undefined.
Graphically, that is represented
as an asymptote.

Vocabulary:
Inverse
variation
– as the input increases, the output decreases, but does not necessarily ever
reach zero
Hyperbola – the shape created
by the graph of an inverse variation function
Asymptotes
–
the imaginary lines that the graph of an inverse variation function approaches,
but never intersects
Don’t
forget:
Radical,
Radicand,
Quadratic, Hypotenuse; Legs, Midpoint
Life Lessons:
·
If you can, get rid of the most difficult obstacle first. But remember, sometimes you have to get your
desk ready before you do anything. Clear out the radical, but make sure it is
isolated first.
·
Sometimes you need to know your goal, analyze the information in
front of you, and make a decision about your path towards that goal, which may
include multiple options.
·
Paying attention to details can make or break a task; making a
problem seem impossible when it is not at all. Dropping a negative can make a
simple two solution quadratic look un-solve-able.
·
If information you need is not given, you need to go get it.
·
Take
a look again! You don’t think that polynomial is factorable? Did you try difference of squares?
·
Absolute
value teaches us that sometimes we have to keep our mind open to two possibilities.
·
Do
not deviate from the straight and narrow path.
·
Pay
attention to details.
·
Debt
is a four letter word.
·
If
something is not given, go find it. The length is not given? Write an equation to calculate it.
·
You
can get a better sense of where you are by looking at the extremes.
·
Before
you believe that something actually affects you, make sure you are actually
a
function of it. For example, does the amount of G2 you drink actually affect your
performance?
·
Reset.
·
If you change what you put
in, you change what you get out. Corollary:
If you don’t change what you put it, you won’t change what you get out.
·
Focus on the most important
thing first.
Magis:
·
Make “life lessons”
posters
