The standard form of equation of parabola is (x-h)^2=4p(y-k) where the directrix is y=k-p and the vertex is as point (h,k).
Thus given that the vertex is at (0,0)
y=k-p
the value of p will be:
-4=0-p
p=4
thus the equation will be:
(x-0)^2=4*4(y-0)
x^2=16y
hence;
y=1/16x^2
the answer is y=1/16x^2
Answer:
k = 9
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to 8
m = 
with (x₁, y₁ ) = (- 1, 1) and (x₂, y₂ ) = (0, k)
m = 
= k - 1 = 8 ( add 1 to both sides )
k = 9

➷ I'm assuming the answer is to be left in algebraic form.
Perimeter = length + length + width + width or (2 x length) + (2 x width)
Substitute the values in:
Perimeter = 2(3x - 5y - 4z) + 2(x - 3y + 5z)
Simplify:
Perimeter = 6x - 10y - 8z + 2x - 6y + 10z
Perimeter = 8x - 16y + 2z <== this is the answer

F(x) - g(x)
becomes
(3x + 2) - (x - 3)
which is
3x + 2 - x + 3
then add like terms
2x + 5
so f(x) - g(x) = 2x + 5
and it's domain should be all real numbers
