Logarithm graph: y=In(-x)?

Question

how does the graph y=In(-x) look like?

is there any graphing tool website where i can go that will show me how this graph look like?!? thanks to the kind ppl who bother answering my question.

Answer 1

Geez, why do you need a website graphing tool.   Grab a piece of paper, you know that ln 1 is 0 therefore when x = -1, ln -x would be 0.   You know that as -x approaches zero, ln -x approaches negative infinity.  You also know that as -x approaches infinity, so does ln -x just more slowly.   So you just draw a X and a Y axis, make a hash mark at X=-1 and sketch a curve that goes from the mark up and to the left but curving more to the left as well as from the mark to the right and down but never reaching the Y-axis ie.: curving more down.

They didn't let us even have calculators when we were doing logarithms and graphing, if you keep on using calculators and computers, you'll never understand math because you'll never be trying to imagine math.   The differential equations for the Boeing 747 control systems were solved with a ruler and semi-log graph paper, it was my professor who did those calculations.

Good Luck!

Answer 3

do you know the graph of y = ln(x)?

they have a similarities but since y = ln(x) is in quadrant I, change it by putting it to quadrant II - mirror image comparing these equations.

2nd option:

try to tabulate the values of x and y for that equation, y = ln(-x) where infinity<x<0, because we where trying to put a positive value for ln.

sorry this is the "help" that i can do for you.
