The answer is D. The ones on the left are the domain. The ones on the right which the arrows point to are the range
A because it is a pattern 4 6 4 8 and that is why it is a
Answer:
Step-by-step explanation:
The directrix is a vertical line, so the parabola is horizontal. The focus lies to the left of the directrix, so the parabola opens to the left.
For a left-opening parabola:
x = a(y-k)²+h,
a < 0,
vertex (h,k)
focal length p = 1/|4a|
focus (h-p, k)
directrix: x=h+p
Apply your data
focus (1,-4)
directrix x=2
vertex (1.5,-4).
focal length p = 0.5
a = -1/|4p| = -½
x = -½(y-2)²+ ½
Substitute the variable for the value given.
11 - 3m becomes 11 - 3(2)
Now do the order of operations.
11 - 3(2) =
11 - 6 =
5
So, the answer is 5.
I am unsure but i think the answer is c or a but let me know if i'm right or wrong
