domain of f(x)=-2x^2+8x-5

domain

f (x) = - 2 x^{2} + 8 x - 5

- \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

\frac{4}{x + 8}

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

x^{2} - 49

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

x^{2} - 5 x - 14
