domain of f(x)=(2x^2-x-4)/(x^2+9)

domain

f (x) = \frac{2 x ^{2} - x - 4}{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

f (x) = 2 x^{3} - 3 x^{2} + 8 x - 4

f (x) = tan (2 x - 2 π)

y + 3 = 7 (x - 2)

y = x^{2} - 3

x + 4
