Determine the domain D and range R of each relation, and tell whether the relation is a function. Assume that a calculator graph extends indefinitely and a table includes only the points shown.

Use the intersection-of-graphs method to approximate each solution to the nearest hundredth.

$$4(0.23 x+\sqrt{5})=\sqrt{2} x+1$$

Write each equation in the form y=mx+b. Then, using your calculator, graph the line in the window indicated.

$$2 y-5 x=0$$

$[-10,10]$ by $[-10,10]$

Give the values of Xmin, Xmax, Ymin, and Ymax for each screen, given the values for Xscl and Yscl. Use the notation described in this section.

Xscl = 5, Yscl = 1

Find the slope (if defined) of the line that passes through the given points.

(-4, -3) and (5, 0)

The rate at which impulses are transmitted along a nerve fiber is directly proportional to the diameter of the fiber. If the rate for a certain fiber is 40 meters per second when the diameter is 6 micrometers, what is the rate if the diameter is 8 micrometers?

Production of DVDs A company produces high-definition DVDs of live concerts. The company places an ad in a trade newsletter: The cost of the ad is $150. Each DVD costs$30 to produce, and the company charges $37.50 per DVD. Use this information to work Exercise given below.

The graph shows y=C(x) and y=R(x). Discuss how the graph illustrates when the company is losing money, when it is breaking even, and when it is making a profit.
