Expert Solution

Answer to Problem 47E

The domain of the function f(x)=1x3 is (,3)(3,)

Explanation of Solution

Given information:Consider the function f(x)=1x3

Calculation:

Recall the domain of a function is the set of input or argument values for which the function is real and defined.

Assume a function from real values to real values as shown in the figure below:

  Precalculus: Mathematics for Calculus - 6th Edition, Chapter 2.1, Problem 47E

From the above graph, the negative values of x to x=3 without including it to the rest of all real numbers.

Thus, the domain of the function f(x)=1x3 is (,3)(3,)
