Answer:
-∞ ; x = 3
Step-by-step explanation:
The graph tends toward -∞ as x approaches 3 from the left. Thus there is a vertical asymptote at x=3, the value of x that makes the denominator zero.
Answer:
(2, 120° )
Step-by-step explanation:
To convert from rectangular to polar form, that is
(x, y) → (r, Θ ), use
r =
Θ = (
)
here (x, y ) = (- 1, )
r = )^2
= =
= 2
Θ = (
) = 60° ← related acute angle
Note (- 1, ) is in the second quadrant so Θ must be in the second quadrant.
Θ = 180° - 60° = 120°
(- 1, ) → (2, 120°)
