Question 824924: I am doing a LOG graph and have found the one point and the vertical asymptote but need to find the x-intercept.
The problem is...
f(x)= log(x-1)-2
I have the vertical shift at down 2 and the horizontal shift at right one. The vertical asymptote is 1 and the point is (2,-2)

The x-intercept is the x value where y=0 , because the x-axis is the y=0 line.
0=log%28%28x-1%29%29-2
2=log%28%28x-1%29%29
10%5E2=x-1
100=x-1
100%2B1=x
highlight%28x=101%29
