domain of f(x)=(11x^2+x)/(x^2+3)

domain

f (x) = \frac{11 x ^{2} + x}{x ^{2} + 3}

- \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

y = \frac{x}{( x + 4 ) ( x - 9 )}

f (x) = - 0.0005 x^{3} + 60 x

f (x) = - 2 x^{3} - 12 x + 1

f (y) = \frac{4}{( y - 2 )}

f (x) = h (x) = 6 x + 5 x - 3
