8.2 GRAPHING RATIONAL FUNCTIONS: HYPERBOLAS

PARENT FUNCTION:

VERTICAL ASYMPTOTE:

HORIZONTAL ASYMPTOTE:

DOMAIN: RANGE:

𝑦=1𝑥

𝑥=0

𝑦=0

𝑥≠0 𝑦 ≠0

8.2 GRAPHING RATIONAL FUNCTIONS: HYPERBOLAS

SIMPLE TRANSLATIONS OF THE PARENT FUNCTION:

VERTICAL ASYMPTOTE:

HORIZONTAL ASYMPTOTE:

DOMAIN: RANGE:

𝑦=𝑎𝑥

𝑥=0

𝑦=0

𝑥≠0 𝑦 ≠0

𝑎≠ 0

EXAMPLE:

8.2 GRAPHING RATIONAL FUNCTIONS: HYPERBOLAS

OTHER TRANSLATIONS OF THE PARENT FUNCTION:

VERTICAL ASYMPTOTE:

HORIZONTAL ASYMPTOTE:

DOMAIN: RANGE:

𝑦=𝑎

𝑥−𝒉+𝒌

𝑥=h

𝑦=𝑘

𝑥≠h 𝑦 ≠𝑘

EXAMPLE:

8.2 GRAPHING RATIONAL FUNCTIONS: HYPERBOLAS

OTHER RATIONAL FUNCTIONS:

VERTICAL ASYMPTOTE:

HORIZONTAL ASYMPTOTE:

DOMAIN: RANGE:

𝑦=𝑎𝑥+𝑏𝑐𝑥+𝑑

𝑥=𝑑𝑐

𝑦=𝑎𝑐

𝑥≠𝑑𝑐

𝑦 ≠𝑎𝑐

EXAMPLE:
