text: The same way you graphed others: substitute for x, solve for y\nIn this case try x values that will give you a whole number for the logarithm. You should notice a steep curve on the graph like an exponential graph.\n\nThe log2 (x) means 2^(what power?)=(your x input)\n\nFor example, if you have x as 1, you will get -2+0=-2 for y\n                                 if x is 4, you get -2+2=0 for y\n                                 if x is 8, you get -2+3=1 for y
