Question

What is the excluded value?

a/b-2

1. a=0
2. b=2
3. b=-2
4. none of the above

Answer 1

b - 2 = 0 since you cannot divide by 0
b = 2 solve for b. this is where the function is undefined

Answer 2

Answer: The correct option is (2)
`b=2.`

Step-by-step explanation: We are given to find the exclude value for the following algebraic expression:

`E=(a)/(b-2)~~~~~~~~~~~~~~~~~~~~~~(i)`

We know that

for a rational expression, we must exclude those values for which the denominator of the fraction becomes zero.

So, in equation (i), the excluded value will be given by

`b-2=0\\\\\Rightarrow b=2.`

Thus, the required excluded value is
`b=2.`

Option (2) is CORRECT.
