could someone explain to me how to graph these?
#1. y = 4log2x (the 2 is the base)
#2. y = log0.2x^2 (the 0.2 is the base)
and if you do caclulus
but these are log graphs, all log graphs have the same shape (the different bases only dictate how steep the graph is). in the general case, the log graph is asymptotic to the y-axis. it goes from negative infinity on the left, passes through (1,0) and goes to positive infinity. this is always the case unless the graph is shifted horizontally or vertically. neither of these graphs are shifted in such ways, so their graphs will look like the one below
This is my 2th post!!!!!!!!!!!!!
as Jhevon pointed out all log-graphs have the same shape (more or less). If you know the graph of then you get the graphs of other log-function by a vertical dilation (to the x-axis) with a constant scale-factor (not certain if I used the correct expressions here).
to #1: From
As you can see the y-values of y=ln(x) are multiplicated by the constant factor 5.77
