First thing: check that you still remember what $\displaystyle \log_2 x$ means. It means "find the power that when applied to the number 2 gives x". So, if you wanted to calculate $\displaystyle \log_2 8$ the answer to that would be 3 because $\displaystyle 2^3 = 8$. Second thing: when you get a function and you're not sure what it looks like, try putting in some values and seeing what you get, so you get a general idea for how the curve varies. You can choose particular x-values to try and make your life easier. Because we have a log to base 2, throw in some powers of 2. For example, use x-values of 0, 1, 2, 4, 8, 16 and then work out the value of the function for each one. What you'll find is that you'll get values for all numbers apart from 0 and 1... Hint: if your calculator gives an error or you get a divide by zero, that usually indicates an asymptote on the curve.
