Solutions

Chapter 1.1, Problem 27E
To determine

To find: The difference quotient for the given function.

Expert Solution

Answer to Problem 27E

The answerof the function is 1ax

Explanation of Solution

Given information:

The given function is,

  f(x)=1x

Andthisevaluation of the quotient is f(x)f(a)xa for the function.

Concept used:

To represent the function:

A function f is a rule that assigns to each element x in a set D exactly one element called f(x) in a set E

The given function is

  f(x)=1x

And evaluate this f(x)f(a)xa for the function.

Now we calculate f(a) for x in the given function f(x)=1x ,

  f(a)=1a

And f(x)=1x

All values of f(a) and f(x) stand in f(x)f(a)xa

  f(x)f(a)xa=1x1axa=axaxxa=axax×1xa=1ax

Therefore,the answer of the function is 1ax .
