Q

How do you find the x-intercept of a rational function?

A

Simplify first, then set the numerator = 0 and solve for the variable.

106
Q

How do you find the y-intercept of a Rational Function?

A

Simplify first, then plug in 0 for x and solve for y.

107
Q

How do you find the vertical asymptotes of a rational function?

A

Simplify first, then set the denominator = 0 and solve for the variable.

108
Q

How do you find a Horizontal Asymptote for a Rational Function?

A
  1. If the numerator degree is greater than the denominator degree, there is no horizontal asymptote.
  2. If the numerator degree is less than the denominator degree, the horizontal asymptote is y = 0.
  3. If the numerator degree is equation to the denominator degree, then the horizontal asymptote is y= leading coefficient of the numerator divided by the leading coefficient of the denominator.
109
Q

How do you know if you have a slant asymptote in a rational function?

A

The numerator degree is 1 greater than the denominator exponent.

110
Q

How do you find a slant asymptote?

A

Long Division

111
Q

How do you find a hole in a Rational Function?

A

Simplify first. If there are any common factors of the numerator and the denominator, the x-value of the hole is the canceled factor. Set canceled factor = 0 and solve for the x-value. Then, plug in the x into the simplified equation to find the y-value of the hole. Answer is in the form of (x, y).
