Chapter 2.1, Problem 62E
To determine

Find the domain of the function f(x)=x26x

Expert Solution

Answer to Problem 62E

The domain of the function f(x)=x26x is (,6)

Explanation of Solution

Given information: Consider the function f(x)=x26x

Calculation:

For the numerator x2 all real values are acceptable to make the function is real and defined.

Don’t take the square root of a negative number in denominator, so the denominator must have, f(x)>0

  6x>0x<6

Hence the given function is defined for all the values of x in the set of real numbers except of the values greater than 6.

Thus, the domain of the function f(x)=x26x is (,6)
