Find the limit. \(\lim _{x \rightarrow 1^{+}} \frac{2+x}{1-x}\)

Short Answer

Expert verified
The limit is \(-\infty\)

Step by step solution

01

Substitute

Substitute x=1 into the expression \(\frac{2+x}{1-x}\).
02

Evaluate

Evaluate the expression with the substituted value. The denominator becomes 0 (since \(1-1=0\)), which makes the fraction undefined.
03

Identify Limit Type

Since the fraction becomes undefined, this suggests a limit that tends to infinity or -infinity. To check whether it is positive or negative infinity, substitute a value slightly greater than 1 (say, 1.01). The value of the denominator will be negative, suggesting that the limit will be negative infinity.

Compare the values of \(d y\) and \(\Delta y\). \(y=0.5 x^{3} \quad x=2 \quad \Delta x=d x=0.1\)

An employee of a delivery company earns \(\$ 10\) per hour driving a delivery van in an area where gasoline costs \(\$ 2.80\) per gallon. When the van is driven at a constant speed \(s\) (in miles per hour, with \(40 \leq s \leq 65\) ), the van gets \(700 / s\) miles per gallon. (a) Find the cost \(C\) as a function of \(s\) for a 100 -mile trip on an interstate highway. (b) Use a graphing utility to graph the function found in part (a) and determine the most economical speed.

Marginal Analysis, use differentials to approximate the change in cost, revenue, or profit corresponding to an increase in sales of one unit. For instance, in Exercise 29, approximate the change in cost as \(x\) increases from 12 units to 13 units. Then use a graphing utility to graph the function, and use the trace feature to verify your result. \(R=50 x-1.5 x^{2} \quad x=15\)

The management of a company is considering three possible models for predicting the company's profits from 2003 through 2008 . Model I gives the expected annual profits if the current trends continue. Models II and III give the expected annual profits for various combinations of increased labor and energy costs. In each model, \(p\) is the profit (in billions of dollars) and \(t=0\) corresponds to 2003 . Model I: \(\quad p=0.03 t^{2}-0.01 t+3.39\) Model II: \(\quad p=0.08 t+3.36\) Model III: \(p=-0.07 t^{2}+0.05 t+3.38\) (a) Use a graphing utility to graph all three models in the same viewing window. (b) For which models are profits increasing during the interval from 2003 through 2008 ? (c) Which model is the most optimistic? Which is the most pessimistic? Which model would you choose? Explain.
