Question

Ln(x-2)<0 if and only if ....

a) X <3
b) 0 < x <3
c) 2 2 e) X >3

Answer 1

y=lnx has an x-intercept at (0,1).

y=ln(x-2) is a horizontal shift of y=lnx 2 units to the right.... so would shift the x-intercept to x=3.

Does that help?

Answer 2

And the function y=lnx is strictly increasing.
