Y=5x+2
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°)
