domain of-x^2+8x-15

domain

- x^{2} + 8 x - 15

- \infty < x < \infty

Interval Notation

(- \infty, \infty)

Solution steps

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

- \infty < x < \infty

f (x) = \frac{2 x + 5}{3 x ^{2} - 10 x - 8}

f (x) = 20 - \frac{1}{2} x

f (x) = \frac{x + 2}{9 - x ^{2}}

f (x) = 24 x - 2328

20 x - 1740
