This module provides practice problems designed to develop some concepts related to graphing.
The following graph shows the temperature throughout the month of March. Actually, I just made this graph up—the numbers do not actually reflect the temperature throughout the month of March. We’re just pretending, OK?
Give a weather report for the month of March, in words.
Mary started a company selling French Fries over the Internet. For the first 3 days, while she worked on the technology, she lost $100 per day. Then she opened for business. People went wild over her French Fries! She made $200 in one day, $300 the day after that, and $400 the day after that. The following day she was sued by an angry customer who discovered that Mary had been using genetically engineered potatoes. She lost $500 in the lawsuit that day, and closed up her business. Draw a graph showing Mary’s profits as a function of days.
Fill in the following table. Then draw graphs of the functions
$y={x}^{2}$ ,
$y={x}^{2}+2$ ,
$y={x}^{2}-1$ ,
$y=(x+3{)}^{2}$ ,
$y={\mathrm{2x}}^{2}$ , and
$y=-{x}^{2}$ .
$x$
${x}^{2}$
${x}^{2}+2$
${x}^{2}-1$
$(x+3{)}^{2}$
${\mathrm{2x}}^{2}$
$-{x}^{2}$
-3
-2
-1

Now describe in words what happened…
How did adding 2 to the function change the graph?
How did subtracting 1 from the function change the graph?
How did adding three to
$x$ change the graph?
How did doubling the function change the graph?
How did multiplying the graph by –1 change the graph?
By looking at your graphs, estimate the point of intersection of the graphs
$y={x}^{2}$ and
$y=(x+3{)}^{2}$ . What does this point represent?
The nanotechnology is as new science, to scale nanometric

Is there any normative that regulates the use of silver nanoparticles?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
