Answer:
answer is 9
if it is corre t u can start following me.
Answer:
C
Step-by-step explanation:
From any point (x, y) on the parabola the focus and directrix are equidistant.
Using the distance formula
= | y - 5 |
Squaring both sides
(x - 4)² + (y - 1)² = (y - 5)² ← distribute the factors in y
(x - 4)² + y² - 2y + 1 = y² - 10y + 25 ( subtract y² - 10y + 25 from both sides )
(x - 4)² + 8y - 24 = 0 ( subtract (x - 4)² from both sides )
8y - 24 = - (x - 4)² ← add 24 to both sides )
8y = - (x - 4)² + 24 ( divide both sides by 8 )
y = - (x - 4)² + 3
Hence
f(x) = - (x - 4)² + 3 → C
3/2 is the common ratio value
