domain of (3n)/(2+n^2)

domain

\frac{3 n}{2 + n ^{2}}

- \infty < n < \infty

Interval Notation

(- \infty, \infty)

Solution steps

The function has no undefined points nor domain constraints. Therefore, the domain is

- \infty < n < \infty

10 x^{4} - 27 x^{3} - 19 x^{2} + 42 x - 36

f (x) = 36 x^{2} + 84 x + 49

f (x) = 144 x - 2 x^{2}

\frac{x - 7}{6}
