You could use a simple pencil test to figure it out.
Place a pencil vertically on the paper, and move it left to right or vise-versa
When moving it make sure the pencil doesn't hit two points at once if it does it is not a function, but this is not the case
This is a function
When reflecting across the Y axis, the Y values remain the same.
Now if you were reflecting across Y = 0, the x values would just be inverse ( opposite signs).
So this triangle if reflected across Y = 0 the new vertices would be (4,4) (2,3) and (5,2)
Now since the reflection line is y = -1, which is a one unit shift to the left of y = 0, subtract 1 unit from each X value.
The locations are now: A'(3,4), B'(1,3) and C'(4,2)

Answer:
we get rectangular coordinates,
x= 
y = 
Step-by-step explanation:
We have given,
Polar coordinates ,P = (r , θ) = (3 , 
)
We nee to find rectangular coordinates:
Since , x =rcosθ and y = rsinθ
i.e x = 3cos(frac{-pi}{3}[/tex]) = 3×
=
And y = 3sin(frac{-pi}{3}[/tex]) = 3×
=
Hence we get rectangular coordinates,
x=
y =
