Question:

Solution:

Let the following function:


f(d)=\sqrt[4]{7d-8}

if we evaluate this function at the point d=1, we get:


f(1)=\sqrt[4]{7(1)-8\text{ }}\text{ = }\sqrt[4]{7-8\text{ }}\text{ = }\sqrt[4]{-1\text{ }}

note that there is no number that multiplied 4 times gives you -1. Therefore, the value of this function does not exist.

Then, by problem notation, we get that the correct answer is:


\emptyset
