domain of f(x)=log_{4}(x-4)

domain

f (x) = lo g_{4} (x - 4)

x > 4

Interval Notation

(4, \infty)

Solution steps

Find positive values for logs:

x > 4

The function domain

x > 4

f (x) = 4 x^{2} + 8 x - 20

(x + 1)^{2} - 9

x + y = 8

f (x) = x^{2} + 4

lo g_{4} (\frac{x - 3}{x})

What is the domain of f(x)=log_{4}(x-4) ?
The domain of f(x)=log_{4}(x-4) is x>4
