1.Determine whether the equation defines a function with independent variable x. If it does, find the domain. If it does not, find a value of x to which there corresponds more than one value of y.

x|y| = x + 9
|y|=(x+9)/x
(A fixed value of x y can take 2 values then the equation does not define a function with x as independent variable.)

2.Use the graph of the function to estimate:

a.f(2)

b.f(–4)

c.All x such that f(x) = 0

a. f(2)=6 due to the fact that (2,6) is in the line

b. f(-4)=0 due to the fact that (-4,0) is in the line

c. x - -4 because from #b f(-4)=0

3.For the following graph:

a.Find the domain of f.

b.Find the range of f.

c.Find the x-intercepts.

d.Find the y-intercept.

e.Find the intervals over which f is increasing.

f.Find the intervals over which f is decreasing.

g.Find the intervals over which f is constant.

h.Find any points of discontinuity.

a. F(x) is a parabola so f(x) = ax2+bx+c and the domain of all polynomials are real numbers because f(x) can be computed for every x real. The domain is R.

b. Vertex is (1,4) and f has a maximum there, then f(x)< for every x real and for every y< we can find x/f(x) = y. The range is -00,4)

c. The x-intercepts of the graph are (-1,0) and (3,0).

d. The y intercept of the graph is (0,3)

e. f is increasing from -00 to the x-coord of the vertex to +00 so f is increasing in (-00,4)

Abstract
In today’s Health Care arena where economics is failing and healthcare workers are looking for a reason to stay in the business, it is important to look at every tool available to make that happen. Multi-skilling is a unique tool available that if used correctly could combine technical and administrative duties...

...The Top 5 Reasons to
be a Jack of AllTrades
Tim Ferriss
#5 | “Jack of AllTrades, Master of None” is an Artificial Pairing
It is entirely possible to be a jack of alltrades, master of many. How? Specialists overestimate the
time needed to “master” a skill and confuse “master” with “perfect”…
Generalists recognize that the 80/20 principle applies to...

...devices it has greatly changed corrections. Corrections all over the country have used cameras to help correctional officers. Also, many use electronic “anklets” or bracelets that act as a GPS transponder so that correction officials can track and pinpoint the location of an inmate. I have also heard that correction officials have told NIJ that they would like to be able to use a handheld wave portal that can identify objects hidden under clothing. All of these new...

...prerequisite to good citizenship, in that it helps citizens make good decisions and deal with demagogues who would delude them. Roger Solder writes that in a democracy, where the demands of good citizenship are placed upon all, "only the common schools can provide to all the education that all need. Science literacy is also frequently touted as a key to good citizenship. Good citizenship is sometimes viewed as requiring both intellectual skills (such...

...What is free trade? Many American’s have a broad and sometimes-false idea of what free trade actually is. Free trade “refers to the economic philosophy and practice of reducing barriers such as tariffs, taxes, subsidies and quotas so that raw materials, goods and services can move unhampered across national borders.” (68) Various options have arisen about whether or not free trade benefits developing counties or not. I believe that free...

... Throughout history different regions have been able to trade with other areas across the continents. Many factors helped facilitate this trade. Among these factors were the laws of supply and demand, the presence of middlemen, and common religions. Under the influence of these factors, silk, jade, dye, horses, and many other goods were traded throughout Asia, Africa, and Europe. Not only did these factors increase trade, but it also helped...
