00:00 Find the domain of substitution
00:03 Substitution domain exists, to ensure we don't divide by 0
00:06 Meaning the denominator in the fraction must be different from 0
00:09 We will use this formula in our exercise
00:19 We will isolate X to find the domain of substitution
00:22 This is the domain of substitution
00:25 And this is the solution to the question

Step-by-Step Solution

To determine the domain of the expression 16+82x 16 + \frac{8}{2x} , we need to ensure the expression is defined by avoiding division by zero.

The crucial part of this fraction is the denominator, 2x 2x . A fraction is undefined when its denominator equals zero. Therefore, we set the denominator equal to zero and solve for x x :

  • Equation: 2x=0 2x = 0
  • Solution: x=0 x = 0

This means the expression is undefined when x=0 x = 0 . Hence, the domain of this expression is all real numbers except zero.

So, the domain of the expression is all x x such that x0 x \neq 0 .

The correct multiple-choice answer is:

x0 x \neq 0

Answer

x0 x\neq0
