Flashcards in Ch 8.3 Deck (14):
1

X intercepts

Numerator equal zero

2

Vertical asymptote

Denominator

3

M is
N is

M is numerator degree
N is denominator degree

4

M

Y=0

5

M=n

Y= Am/Bn
(Constants or coefficients)

6

M>n

No horizontal asymptote
End behavior
LC= m/n
Degree= m-n

7

Directly

Y=ax

8

Inverse

Y=a/x

9

Joint

Y=azx

10

To check variation check

The opposite of what want to know
So if want to know if direct y=ax
Test y/x=a
If want to know inverse
Yx=a

11

When graphing y=a/x
What are asymptotes
How to graph

X=0
Y=0
Input out put for table
Draw branches

12

When graphing
y=a/x-h +k

X=h asymptote
Y=k asymptote
Then input out put
Branches

13

Graphing y=ax+b/cx+d +e

Denominator equal to zero for vertical asymptote
Horizontal is y=a/c +e

14

How to graph y= 3x^2/x^2

1) x intercepts are numerator=0
2) vertical asymptotes denominator=0
Set table
Plot points
