Question

Suppose the growth curve of catfish in Oxford is given by: f(x)=0.5e^0.2t, where y= length, t= time (in week). Determine the length at 4 weeks.

Answer 1

Since f(x) or y is defined as the length, simply sub t = 4 into the function

f(4) = .5 e^(.2*4) = .5 e^.8 = appr 1.113 units of length
