Question: how to find x and y intercepts of logarithmic functions?
Answer: All logarithmic functions will have a vertical asymptote and pass through the point at distance 1 from the vertical asymptote in the direction it opens up. This point will always be the x intercept. To find it, we can set y equal to 0 and solve for x. Let's look at the graph of f(x) = ln(5-x).
