Chapter 2: Problem 40

Determine whether each statement makes sense or does not make sense, and explain your reasoning. The graph of my function is not a straight line, so I cannot use slope to analyze its rates of change.

Short Answer

Expert verified
The statement does not make sense. Although the function is not linear and its slope is not constant, slope can still be used to analyze its rates of change at a particular point by using calculus.

Step by step solution

01

Definition of Slope

The slope of a line is a measure of the change in y for each unit change in x. It is usually represented by the letter 'm'. Slope is often related to steepness or gradient of the line. For linear functions, the graph is a straight line, thus their slope is constant.
02

Understanding Rate of Change for Non-Linear Functions

Rate of change for a function refers to the speed at which the y-value of a function changes for each change in the x-value. In other words, it signifies how a function behaves with respect to changes in variables. For non-linear functions, this rate of change is not constant, but it can still be analyzed at a given point.
03

Analysis of the Statement

While it's true that for a non-linear function the slope is not constant, that doesn't mean that it cannot be used to analyze its rates of change. By using calculus (specifically, the concept of derivative), one can calculate the slope of the tangent line at a given point on a curve, providing a measure of the rate of change at that point. Therefore, the statement does not make sense.

Graph \(y_{1}=x^{2}-2 x, y_{2}=x,\) and \(y_{3}=y_{1} \div y_{2}\) in the same \([-10,10,1]\) by \([-10,10,1]\) viewing rectangle. Then use the TRACE \(]\) feature to trace along \(y_{3} .\) What happens at \(x=0 ?\) Explain why this occurs.

Exercises \(103-105\) will help you prepare for the material covered in the next section. Let \(\left(x_{1}, y_{1}\right)=(7,2) \quad\) and \(\quad\left(x_{2}, y_{2}\right)=(1,-1) . \quad\) Find \(\sqrt{\left(x_{2}-x_{1}\right)^{2}+\left(y_{2}-y_{1}\right)^{2}} .\) Express the answer in simplified radical form.

Express the given function \(h\) as \(a\) composition of two functions \(f\) and \(g\) so that \(h(x)=(f \circ g)(x)\). $$h(x)=|3 x-4|$$

If equations for \(f\) and \(g\) are given, explain how to find \(f-g\)

Determine whether each statement is true or false. If the statement is false, make the necessary change(s) to produce a true statement. Prove that if \(f\) and \(g\) are even functions, then \(f g\) is also an even function.
