The function

is used in population models to give the size of the next generation (ƒ(x)) in terms of the current generation (x).
(a) What is a reasonable domain for this function, considering what x represents?
(b) Graph this function for λ = a = b = 1.
(c) Graph this function for λ = a = 1 and b = 2.
(d) What is the effect of making b larger?

f(x) Xx 1 + (ax)
