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

domain

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

- \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^{2} - 1) - (4 x + 8)

y = 2 x^{2}

y = - 8 x

(1, 3), (- 2, - 3)

\frac{2 x}{( x ^{2} - 1 )}
