= 10
< 13
B
4 × 13 = 52 > 13
C

< 13
D
× 13 = 1 × 13 = 13
Band D are equal to or greater than 13
Refer to the diagram shown below.
The distance, d, from the focus to a point P (x,y) is equal to the distance from the directrix to P.
Therefore
d² = (6 - y)²
= (x + 2)² + y²
That is,
36 - 12y + y² = (x + 2)² + y²
12y = -(x + 2)² + 36
The equation of the parabola is
y = -(1/12)(x + 2)² + 3
It may be written as
-12(y - 3) = (x + 2)²
The leading coefficient -1/12 is negative, therefore the curve opens downward.
Answer:
The equation is (x + 2)² = -12(y - 3).

Answer:
The correct option is 4.
Step-by-step explanation:
The given function is
The graph of another function g(x) is shown in give figure.
Choose any point from the given intervals and check whether the function g(x) is greater than h(x) or not.
For interval .
Put x=-2 in the given function h(x).
The value of h(x) at x=-2 is 7.75.
From the given graph it is noticed that the value of g(x) at x=-2 is 1.
Since g(x)<h(x) at x=-2, therefore option 1 is incorrect.
For interval and
Put x=0 in the given function h(x).
The value of h(x) at x=0 is 7.
From the given graph it is noticed that the y-intercept of g(x) is 3.
Since g(x)<h(x) at x=0, therefore option 2 and option 3 are incorrect.
For interval .
Put x=2 in the given function h(x).
The value of h(x) at x=2 is 4.
From the given graph it is noticed that the value of g(x) at x=2 is more than 10.
Since g(x)>h(x) at x=2, therefore option 4 is correct.
