domain of f(x)=2x^2+9

domain

f (x) = 2 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

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

f (x) = 7 sin (5 x + 4)

y = \frac{2 x ^{2}}{x ^{2} - 1}

f (x) = (\frac{- 9 - 7 x}{3})

f (x) = 8 x - 12
