20 points for this question:<br><br> Find the domain.
Yuliya22 [10]

Answer:

The Domain D = {y ∈ R / y ≠ \dfrac{b}{2} y ≠ 0}

Step-by-step explanation:

Let ,

f(y) = \dfrac{b^{2} - 4by }{2y^{2} - by } - \dfrac{4y}{b-2y}

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

2y^{2} - by ≠ 0 and b - 2y ≠ 0

∴ y(2y - b) ≠ 0                 and y ≠\dfrac{b}{2}

Either y ≠ 0 or y ≠ \dfrac{b}{2}

∵ 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 ≠ \dfrac{b}{2}
