**Ignore?**

No, only want reals.

Does a graph have to have an X intercept?

To find an x intercept

Set the numerator equal to 0 and solve for x

No, but most it can have is 1.

Does a graph have to have a Y intercept?

To find a y intercept

Substitute 0 for x in denominator and solve

Domain

The ______________________ is all the possible INPUT, X, values.

Substitute x coordinate into simplified expression

To find the y coordinate of a hole

Horizontal Asymptotes

y=0 when degree of denominator > degree of numerator

Vertical Asymptotes

zeroes of denominator

To find vertical asymptotes

Set denominator equal to zero solve for x

No, but can have more than 1

Does a graph have to have a vertical asymptote?

Horizontal Asymptotes occur when

Degree of the numerator is less than the degree of the denominator

The horizontal asymptote is y=0

When the degree of the numerator is less than the degree of the denominator

The horizontal asymptote is y= ratio of leading coefficients

When the degrees of the numerator and denominator are the same

y→HA

When there is a horizontal asymptote the EB is

Slant asymptotes occur when

Degree of the numerator is one more than the degree of the denominator

Synthetic division

To find a slant asymptote

L:y→-∞ R:y→∞

When the slope is positive

L:→∞ R:y→-∞

When the slope is negative

Factor the numerator and denominator.

Step 1 of graphing rational expressions

y=0

If degreevof numerator is less than degree if denominator...

Y=ratio of lead coefficient

If degree of numerator is = degree of denominator. ..

There is no HA but SA is present.

If degree of numerator is greater than degree of denominator. ..

Holes

when same factor occurs in numerator and denominator

X intercepts

Ordered pair

Y intercepts

Ordered pair

Min/max
