I need to find the x-intercept of . It's (?, 0). Can't seem to find it . According to the graph: The line doesn't cross the x-axis anywhere.

make y = 0 and solve for x. Use $\displaystyle a^b= c \Rightarrow b = \log_ac$

$\displaystyle 0 = \log_5(x-1)+4$ $\displaystyle -4 = \log_5(x-1)$ $\displaystyle 5^{-4} = x-1$ $\displaystyle 5^{-4} +1= x$ $\displaystyle \frac{1}{5^{4}} +1= x$ Can you finish it?
Yes . Thanks! Got it. I should have known...
