Definition: A function is a rule that assigns to each input number exactly one output number. The set of all input numbers to which the rule applies is called the domain of the function. The set of all (corresponding) output numbers is called the range.
Notation: if y is a function of x, we write
y = f(x)
Other common symbols for functions include but are not limited to g, h, F, G
y = f(x) = cnxn + cn-1xn-1 + + c1x +c0 where n is a non-negative integer and the ci are constants with cn 0. The number n is called the degree of the polynomial and cn is called the leading coefficient.
Suppose for a particular business, fixed cost is $50/yr and variable cost is depends on the number of units produced, q, such that V(q) = 2q2. Find the total cost function and the total cost of producing 10 units.
A realtor needs to determine the square footage yard space for a piece of property that is for sale. The entire lot is shaped as rectangle and is 200 feet x 300 feet. The home on the lot is 2000 sq. ft. And there is a 10ft. x 20ft. Driveway.
