Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
Truck Rentals The cost C, in dollars, of a one-day truck rental
is modeled by the function C(x) = 0.35x + 45, where x is
the number of miles driven.
(a) What is the cost if you drive x = 40 miles?
(b) If the cost of renting the truck is $108, how many miles
did you drive?
(c) Suppose that you want the cost to be no more than $150.
What is the maximum number of miles that you can
drive?
(d) What is the implied domain of C?
