Solutions

Chapter 2.7, Problem 1E

(a)

To determine

To estimate: The value of f(3) using the graph of f.

Expert Solution

Answer to Problem 1E

The value of f(3) is 0.2.

Explanation of Solution

Estimation:

Draw the slope of the tangent at the point x=3.

Single Variable Calculus: Concepts and Contexts, Enhanced Edition, Chapter 2.7, Problem 1E , additional homework tip  1

The calculation of the slope at x=3 is as follows,

From the Figure 1,

m=1.9+1.73+4=0.2

Thus, f(3)=0.2.

(b)

To determine

To estimate: The value of f(2) using the graph of f.

Expert Solution

Answer to Problem 1E

The value of f(2) is 0.

Explanation of Solution

Estimation:

Draw the slope of the tangent at the point x=2.

Single Variable Calculus: Concepts and Contexts, Enhanced Edition, Chapter 2.7, Problem 1E , additional homework tip  2

From the Figure 2, tt is clear that the tangent to the graph at x=2 is horizontal.

Thus, f(2)=0

(c)

To determine

To estimate: The value of f(1) using the graph of f.

Expert Solution

Answer to Problem 1E

The value of f(1) is 1.

Explanation of Solution

Estimation:

Draw the slope of the tangent at the point x=1.

Single Variable Calculus: Concepts and Contexts, Enhanced Edition, Chapter 2.7, Problem 1E , additional homework tip  3

From the Figure 3, Slope of AB

m=1+20.5+1.5=1

Thus, f(1)=1.

(d)

To determine

To estimate: The value of f(0) using the graph of f.

Expert Solution

The value of f(0) is 2.

Explanation of Solution

Estimation:

Draw the slope of the tangent at the point x=0.

Single Variable Calculus: Concepts and Contexts, Enhanced Edition, Chapter 2.7, Problem 1E , additional homework tip  4

From the Figure 4, Slope of AB

m=110.51.5=2

Thus, f(0)=2.

(e)

To determine

Single Variable Calculus: Concepts and Contexts, Enhanced Edition, Chapter 2.7, Problem 1E , additional homework tip  6

From the Figure 6, it is clear that the tangent to the graph at x=2 is horizontal.

Thus, f(2)=0.

(g)

To determine

To estimate: The value of f(3) using the graph of f.

Expert Solution

Answer to Problem 1E

The value of f(3) is 0.2.

Explanation of Solution

Estimation:
