domain of (-4x^2+3)+(1/(2x^2+1))

domain

(- 4 x^{2} + 3) + (\frac{1}{2 x ^{2} + 1})

- \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

2 x - 9

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

f (x) = \frac{5 x + 14}{6 x ^{2} + x - 2}

f (x) = \frac{x + 9}{x ^{2} - 49}

\frac{3}{3 x + 2 - 3 x - 2}
