domain of f(x)=log_{5}(x-1)

domain

f (x) = lo g_{5} (x - 1)

x > 1

Interval Notation

(1, \infty)

Solution steps

Find positive values for logs:

x > 1

The function domain

x > 1

f (x) = 20

f (x) = 3 t

f (x) = \frac{x}{x ^{2} + 6 x + 8}

f (x) = \frac{x + 3}{x - 4}

f (x) = (\frac{2 x ^{2} - 6 x + 4}{- 3 x - 5})

What is the domain of f(x)=log_{5}(x-1) ?
