What is the equation of a parabola whose vertex is (0, 5) and whose directrix is x = 2? y2 = 8(x − 5) 8(y − 5) = x2 (y − 5)2 = 8x (y − 5)2 = -8x

Step-by-step explanation:

vertex is (0, 5) and whose directrix is x = 2

Vertex (0,5), x=0 and y=5

The distance between x=0 and x=2 is 2 units

The distance between vertex and directrix is P

p= 2

General equation of horizontal parabola is

h=0, y= 5, p=2

ian gone lie this got me confused

step-by-step explanation:

answer:

at time x=0 we have 1000, at time x=1 we have 2000, at time x=2 we have 4000.  

so that's an initial value of 1000 and a ratio of 2,

y = 1000 (2^x)

hope this !
