In a given experiment, measurements taken showed that the number of

elements of a bacterial population decreased with time, so

approximately exponential:

time - 0 - 1 - 2 - 3 - 4 - 5 - 6 - 7 -8 - 9 - 10

amount - 419 - 274 - 181 - 122 - 85 - 61 - 46 - 36 - 30 - 26 - 24

Try adjusting the points above by a function of type:

My solution:

I find z(x) = ln(x) (*ln of each amount*)

g1(x) = 1; g2(x) = x;

I find:

a11 = 11

a12=a21 = 55

a22 = 385

b1 = 47,4564

b2 = 205,1156

Matrix x Vector(beta1 and beta2) = Vector (b1 and b2)

a1 = expoent(beta1) = 322,37

a2 = beta2 = -0,2923

Is that right?
