This is
This says y is a log. A log is an exponent to some base. The base is 2.
You can rewrite it as
Now pick some values of y and find x.
y = 0
x = 1
-----
y = 1
x = 2
-----
y = 3
x = 8
-----
y = 4
x = 16
-----
y = -1
x = 1/2
-----
y = -2
x = 1/4
------
you can plot these points. Note that x can never be negative
