domain of (2x^2-x-7)/(x^2+9)

domain

\frac{2 x ^{2} - x - 7}{x ^{2} + 9}

- \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

lo g_{\frac{1}{2}} (- x + 2) + 5

(2, 1), (10, 9)

f (n) = n + 5

f (x) = 1 + 4 + x

f (x) = \frac{1}{x + 8} + 3
