20 points for this question:

find the domain.

The Domain D = {y ∈ R / y ≠ y ≠ 0}

Step-by-step explanation:

Let ,

f(y) = -

The above function would be defined only when the denominator of anyone or both the terms of the function do not become 0 -

≠ 0 and b - 2y ≠ 0

∴ y(2y - b) ≠ 0                 and y ≠

Either y ≠ 0 or y ≠

∵ The domain of a function consists of only those points where the function is defined -

The Domain D consists of all y ∈ Real numbers such that y ≠ 0 and y ≠
