    If we evaluate the function y=\log_2(x) at the given points, we have:

    \log_2(8)=3

    \log_2(4)=2

    \log_2(2)=1

    \log_2(1)=0

    \log_2\left(\dfrac{1}{2}\right)=-1

    In fact, the function y=\log_2(x) returns, for a given number x, the exponent you have to give to 2 to obtain x.

    So, you want to obtain 8, you have to raise 2 to the 3rd power, if you want 4 you have to raise 2 to the 2nd power, and so on.
