This set of exercises will draw on the ideas presented in this section and your general math background. Sketch the graph of \(f(x)=-3 x+2\) by hand. Use it to graph \(g(x)=|f(x)| .\) What is the \(x\) -intercept of the graph of \(g(x) ?\)
This set of exercises will draw on the ideas presented in this section and your general math background. What happens when you try to find the intersection of \(y=x\) and \(y=x+2\) algebraically? Graph the two lines on the same set of axes. Do they appear to intersect? Why or why not? This is an example of how graphs can help you to see things that are not obvious from algebraic methods. Examples such as this will be discussed in greater detail in a later chapter on systems of linear equations.

The sales of portable CD players in the United States held steady in the years
2000 and 2001 , but then slowly declined in the years \(2002-2005\) (Source:
Consumer Electronics Association). The sales are given by the function
$$S(t)=\left\\{\begin{array}{ll}32, & \text { if } 0 \leq t \leq 1
\\\32-3.75(t-1), & \text { if } 1
Sketch by hand the graph of the line with slope \(-\frac{3}{2}\) and \(y\) -intercept \((0,-2) .\) Find the equation of this line.
