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.

Question

Chapter 3.1, Problem 18E

To determine

To find: the independent and dependent variable.

Expert Solution

Answer to Problem 18E

Independent variable: x

Dependent variable: y

Explanation of Solution

Given:

The function y=3.5x+2.8 represents the cost y (in dollars) of a taxi ride of x miles.

Here, the independent variable is x and the dependent variable is y as the cost of taxi ride depends on the number of miles travelled.

To determine

To find: domain and range of function.

Expert Solution

Answer to Problem 18E

Domain: 0≤x≤20

Range: 2.8≤y≤72.8

Explanation of Solution

Given:

The function y=3.5x+2.8 represents the cost y (in dollars) of a taxi ride of x miles.

Since money is sufficient to travel at most 20 miles in taxi.

So, the domain of the given function is: 0≤x≤20

The given function y=3.5x+2.8 is a linear increasing function and it is also continuous.

The smallest output value of this function is achieved at the smallest input value of domain

(x=0) and the largest output value at the largest input value of domain (x=20) .

First substitute x=0 in the function,

y(0)=3.5(0)+2.8=0+2.8=2.8

Now substitute x=20 in the function,

y(20)=3.5(20)+2.8=70+2.8=72.8

Thus, the range is 2.8≤y≤72.8 .
