In Problems 25–32, use the given functions f and g.

$(a) f (x) = 0 (b) g (x) = 0 (c) f (x) = g (x) (d) f (x) > 0$

role="math" localid="1646199855131" $(e) g (x) \leq 0 (f) f (x) > g (x) (g) f (x) \geq 1$

What is the domain of the function $f (x) = \sqrt{x - 3 x^{2}}$ ?

The monthly revenue R achieved by selling

x wristwatches is figured to be $R (x) = 75 x - 0.2 x^{2}$ The monthly cost C of selling x wristwatches is $C (x) = 32 x + 1750$

(a) How many wristwatches must the firm sell to maximize revenue? What is the maximum revenue?

(b) Profit is given as P(x) = R(x) - C(x). What is the profit function?

(c) How many wristwatches must the firm sell to maximize

profit? What is the maximum profit?

(d) Provide a reasonable explanation as to why the answers found in parts (a) and (c) differ. Explain why a quadratic function is a reasonable model for revenue.

A is used to help us to see the type of relation, if any, that may exist between two variables.
