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

domain

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

- \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) = \frac{x ^{2} - 4 x - 12}{x - 2}

\frac{\frac{x}{x ^{2} + 1}}{\frac{x}{x ^{4} - 1}}

f (x) = (x^{6} + 4 x^{3} - 3)

4 x^{2} + 3 x - 2

\frac{( 2 X - 5 )}{( 2 X + 5 )}
