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

domain

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

f (x) = 0. 4^{(5 - x)} - 4

\frac{3 x - 5}{x - 2}

\frac{x ^{2}}{2}

f (x) = \frac{ln ( x )}{x ^{2}}
