Question 53955
This could look like a parabola or an exponential equation or other things (which I don't are what you are looking for.)
Exponential: You need a y-value of zero
(0,1) and (2,4)
y = a(b^x)
1 = a(b^0) which is: 1 = a
y = b^x
4 = b^2
2 = b
~> y = 2^x
But we want 1 day to be 1 second, not 0 days to be 1 second.
~> y = 2^(x - 1)
