Best ResponseYou've already chosen the best response.0if you had ln(x) then it would be 1/x but for log(x) its 1/(x ln10) assuming the base on the log is 10

Best ResponseYou've already chosen the best response.0substituting in 1 for x gives you the slope of the tangent line. because you want a line it can be written as y = mx + b

Best ResponseYou've already chosen the best response.0you have m = 1, and a point (1, 0) so using that you should be able to get an equation for the line and then solve for where it crosses the yaxis
