Rate of Change

The relation between two quantities which displays how much greater one quantity is than another is called ratio.

Slope

The change in the vertical distances is known as the rise and the change in the horizontal distances is known as the run. So, the rise divided by run is nothing but a slope value. It is calculated with simple algebraic equations as:

Question

Chapter 2.4, Problem 21E

(a)

To determine

To find: The slope of the curve y=1x−1 at x=a.

(a)

Expert Solution

Answer to Problem 21E

The slope of the curve y=1x−1 at x=a is −1(a−1)2.

Explanation of Solution

Given information:

The curve is y=1x−1 and point is x=a.

Calculation:

The formula for the slope of the curve f(x) at (a,f(a)) is limh→0f(a+h)−f(a)h.

The function is given as f(x)=1x−1.

Substitute a+h for x in the function.

f(a+h)=1a+h−1

Substitute a for x in the function.

f(a)=1a−1

Substitute 1a+h−1 for f(a+h) and 1a−1 for f(a) in the formula for slope.

limh→0f(a+h)−f(a)h=limh→01a+h−1−1a−1h=limh→0a−1−(a+h−1)(a−1)(a+h−1)h=limh→0−hh(a−1)(a+h−1)=limh→0(−1(a−1)(a+h−1))

Further simplify.

limh→0f(a+h)−f(a)h=−1(a−1)(a+0−1)=−1(a−1)2

Therefore, the slope of the curve y=1x−1 at x=a is −1(a−1)2.

(b)

To determine

To find: The change in the tangent at x=a as the value of a changes.

(b)

Expert Solution

Answer to Problem 21E

The slope of the tangent increases as the value of a increases and the tangent is steeper near the point a=1.

Explanation of Solution

Given information:

The curve is y=1x−1 and point is x=a.

Calculation:

As calculated in part (a), the slope of the curve y=1x−1 at x=a is equal to −1(a−1)2.

So, the slope of the tangent of the curve is always negative and the value of slope of tangent increases as the value of a increases. The tangent is steeper near the point a=1.

Therefore, the slope of the tangent decreases as the value of a increases.
