2u! Literal equations are very hard I suggest using math way.com or photo math regarding these problems
Ok, so from previous question
(x-h)^2=4p(y-k)
distance from focus to directix is 2
2/2=1=p
1>-1
focus is above the vertex
1 unit down from (0,1) is (0,0)
vertex at (0,0)
since focus is above, p is positive
(x-0)^2=4(1)(y-0)
x^2=4y
4y=x^2
divide both sides by 4
y=(1/4)x^2
f(x)=1/4x^2
2nd one is answer
X= 1 Y=4

Answer:
- 3 1/4
Step-by-step explanation:
-2 1/2 - x = -5 3/4
(Add 2 1/2 to both sides)
- x = 3 1/4
(Make x positive)
x = - 3 1/4
