Answer:

D,E are not functions

Step-by-step explanation:

A function is a relation in which every input has not more than one output.But the output of the inputs may be same.Here in D the input 1 has 4 different outputs as 1,2,3,4.So its not a function.Similarly in E 6 has 2 outputs as 2 and -1.For remaining sets the inputs has only one output.so they are functions.

wel

f(0) = $\sqrt{2}$ · $\sqrt{2^{2(0) - 1}}$

= $\sqrt{2}$ · $\sqrt{2^{0 - 1}}$

= $\sqrt{2}$ · $\sqrt{2^{- 1}}$

= $\sqrt{2}$ · $\frac{1}{\sqrt{2}}$

= $\frac{\sqrt{2}}{\sqrt{2}}$

= 1
