Question

For what values (cases) of the variables the expression does not exist: a/2x−4

Answer 1

x=2

Explanation:

Given the expression:
`(a)/(2x-4)`

The expression is undefined or "does not exist" when the value of the denominator equals zero.

Therefore, set the denominator of the function equals to zero to find the values at which it does not exist.

2x-4=0

2x=4

x=2

Therefore, at x=2, the function is undefined.
