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

domain

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

x - 6

y = \frac{23}{5} x - 12

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

f (x) = - 5 (x + 1)^{2} - 5

x^{4} + 8 x^{3}
