Chapter 2, Problem 18RE
To determine

Find the domain of the function f(x)=3x2x+1

Expert Solution

Answer to Problem 18RE

The domain of the function f(x)=3x2x+1 is [(1,0)(0,)]

Explanation of Solution

Given information: Consider the function f(x)=3x2x+1

Calculation:

We can’t take the square root of a negative number, so we must have f(x)0

  x+10x1

And for denominator,

A rational expression is not defined when the denominator is 0.

Since x0

Hence the given function is defined for all the values of x in the set of real numbers except of the value x=0

Thus, the domain of the function f(x)=3x2x+1 is [(1,0)(0,)]
