Chapter 1: Q9E (page 9)

The graph shown gives the weight of a certain person as a function of age. Describe in words how this person’s weight varies over time. What do you think happened when this person was 30 years old?

Short Answer

Expert verified

The person's weight is decreasing over time, and the possible reasons are the person must be on the diet, in exercise, and maybe ill health.

Step by step solution

01

Given information 

Consider the given graph.

02

Describe how a person’s weight varies over time, and what happened when this person was 30 years old

It can be observed that the person’s weight is taken along the y-axis, and age is taken on the x-axis.

The graph shows that the person’s weight rises between the age group 0-20, and the increase in weight is like uphill.

From 20-30, the weight of the person slightly increases by about \(160\) pounds.

At the start of their 30s, his weight dropped quickly to around \(120\) pounds, and at age\(35\), the weight increased rapidly to about \(170\) pounds.

For the next \(30\) years, the person’s weight gradually increased to about \(190\) pounds.

Therefore, the possible reasons for the loss of weight at the age of \(30\) are the person must be in the diet, in exercise, and maybe ill health.

Find the domain of the function

\(h\left( x \right) = \frac{1}{{\sqrt(4){{{x^2} - 5x}}}}\)

Evaluate the difference quotient for the given function. Simplify your answer.

\(f\left( x \right) = \frac{1}{x}\), \(\frac{{f\left( x \right) - f\left( a \right)}}{{x - a}}\)

If H is the Heaviside function defined in Example 6, prove using definition 4, that \(\mathop {\lim }\limits_{t \to 0} \;H\left( t \right)\;\;\)does not exist. (Hint: use an indirect proof as follows. Suppose that the limit is L. Take \({\bf{\varepsilon = }}\frac{{\bf{1}}}{{\bf{2}}}\;\;\)in the definition of a limit and try to arrive at a contradiction.

Suppose the graph of\({\bf{f}}\)is given. Write equations for the graphs that are obtained from the graph of\({\bf{f}}\)as follows.

(a) Shift 3 units upward.

(b) Shift 3 units downward.

(c) Shift 3 units to the right.

(d) Shift 3 units to the left.

(e) Reflect about the\({\bf{x}}\)-axis.

(f) Reflect about the\({\bf{y}}\)-axis.

(g) Stretch vertically by a factor of 3.

(h) Shrink vertically by a factor of 3

Prove the statement using the\(\varepsilon \) \(\delta \)definition of a limit.

\(\mathop {\lim }\limits_{x \to 2} \frac{{{x^2} + x - 6}}{{x - 2}} = 5\)
