domain of f(x)=log_{10}(3x)2-x-20

domain

f (x) = lo g_{10} (3 x) 2 - x - 20

x > 0

Interval Notation

(0, \infty)

Solution steps

Find positive values for logs:

x > 0

The function domain

x > 0

f (x) = - 3 2 x + 3 - 1

f (x) = \frac{4}{( x - 1 )} + 1

g (x) = 4 x - 1 h (x) = x - 3

g (x) = \frac{( x + 7 ) ^{2}}{6 x - 2}

\frac{ln ( x ^{2} )}{x ^{2} - 1}
