Solutions

Chapter 1.2, Problem 7E
To determine

To find: The common term of all the members of the family of linear function f(x)=cx ; sketch the members of the family.

Expert Solution

Answer to Problem 7E

The members of the family of linear function f(x)=cx have the common slope m=1 and y-intercept is c.

Explanation of Solution

Consider the function y=cx .

Here, the slope (m) of the function is −1 and y-intercept is c.

Obtain the equations of the function for various c values.

If c=1 , then y=1x .

If c=1 , then y=1x .

If c=0 , then y=x .

If c=3 , then y=3x .

Draw the graph of above equations as shown below in Figure 1.
