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

domain

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

∣ 4 x - 3 ∣

f (x) = lo g_{4} (x + 2)

3 x^{2} - 3

\frac{572}{x ^{2} - x}

\frac{4 x + 5}{7}
