domain of log_{10}(x^2-2x-15)

domain

lo g_{10} (x^{2} - 2 x - 15)

x < - 3 or x > 5

Interval Notation

(- \infty, - 3) \cup (5, \infty)

Solution steps

Find positive values for logs:

x < - 3 or x > 5

The function domain

x < - 3 or x > 5

2 x - 4

\frac{x + 5}{x - 7}

x^{35}

y = ln (x^{2} - 14 x)

f (x) = - 1.33 x^{2} + 48 x
