Answer:

Domain is; d is a set of non - zero integers.

Range will be p(d) for values of; d > 0 or d < 0

Explanation:

In Mathematics, the domain is the set of all input values in a given function while range is the set of output values for each given input function.

Thus, looking at the function given;

p(d) = -(28.2/d) + 0.859

It is clear that if d = 0, we will have an undefined solution as any number divided by zero is undefined.

Thus, the domain is; d is a set of non - zero integers.

Range will be p(d) for values of; 0 < d < 0
