Chapter 1: Problem 1

Use a graphing utility to graph the function and visually estimate the limits. \(h(x)=x^{2}-5 x\) (a) \(\lim _{x \rightarrow 5} h(x)\) (b) \(\lim _{x \rightarrow-1} h(x)\)

Short Answer

Expert verified
The exact limits can't be given as we are visually estimating from the graph. However, the limit of \(h(x)=x^{2}-5 x\) as \(x\) approaches 5 and -1 will be the value the function \(h(x)\) seems to be heading towards at \(x=5\) and \(x=-1\) respectively, from the visual analysis of the graph.

Step by step solution

01

Graphing the function

Use a graphing utility to plot the function \(h(x)=x^{2}-5 x\). This will give a visual representation of how the function behaves for different \(x\) values.
02

Estimating limit as \(x\) approaches 5

Analyzing the graph, as \(x\) gets closer and closer to 5 from both sides (left and right), find where the function value \(h(x)\) is heading. That will be the estimated limit as \(x\) approaches 5.
03

Estimating limit as \(x\) approaches -1

Similarly, observe from the graph what value the function \(h(x)\) is heading towards as \(x\) gets closer and closer to -1 from both sides. That value will be the visually estimated limit as \(x\) approaches -1.

Write the expression in algebraic form. \(\sin (\operatorname{arcsec} x)\)

Determine whether the statement is true or false. If it is false, explain why or give an example that shows it is false. If \(f(x)=x^{n}\) where \(n\) is odd, then \(f^{-1}\) exists.

Rate of Change A patrol car is parked 50 feet from a long warehouse (see figure). The revolving light on top of the car turns at a rate of \(\frac{1}{2}\) revolution per second. The rate \(r\) at which the light beam moves along the wall is \(r=50 \pi \sec ^{2} \theta \mathrm{ft} / \mathrm{sec}\) (a) Find \(r\) when \(\theta\) is \(\pi / 6\). (b) Find \(r\) when \(\theta\) is \(\pi / 3\). (c) Find the limit of \(r\) as \(\theta \rightarrow(\pi / 2)^{-}\)

In Exercises \(35-38\), use a graphing utility to graph the function and determine the one-sided limit. $$ \begin{array}{l} f(x)=\frac{x^{2}+x+1}{x^{3}-1} \\ \lim _{x \rightarrow 1^{+}} f(x) \end{array} $$
