domain of f(x)=log_{e}(9x^2-18x+18)

domain

f (x) = lo g_{e} (9 x^{2} - 18 x + 18)

- \infty < x < \infty

Interval Notation

(- \infty, \infty)

Solution steps

Find positive values for logs:

- \infty < x < \infty

The function has no undefined points nor domain constraints. Therefore, the domain is

- \infty < x < \infty

f (x) = ln (5 x - 4)

f (x) = \frac{x + 3}{x - 9}

f (x) = 8 x^{2} - 79 x + 63

f (x) = 2 ln (- 4 x + 7) - 2

f (x) = 10 x - 25
