domain of f(x)=x+sqrt(2x+6)=9

domain

f (x) = x + 2 x + 6 = 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

- \frac{1}{3} x + 5

f (x) = \frac{7 x}{x - 6}

[(\frac{x}{x ^{2} - 1}) (1 - 2 x)]^{2}

f (x) = x^{7} + x^{6} - x^{2}

f (x) = - x + 9
