hello

This is what I have written out in Maple, and I have been trying to plot into a graph, but am having no luck at all.  Do you have any advice for what my next step should be. I'm using a simplified version of Brain and Cousens model.

y := (x) -> (d+fx)/(1+h*x^b) , x > 0

b := 2; d := 1; h := 1;

This is the question: Let b = 2, d = 1 and h = 1
