domain of f(x)=-0.5x^2+40x-300

domain

f (x) = - 0.5 x^{2} + 40 x - 300

- \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) = \frac{2}{∣ x - 2 ∣ - 1}

\frac{1}{( 25 ) ^{x} + 4 ( 5 ^{x} ) - 1}

y = 3 (x + 7) (x + 3)

y = \frac{x - 1}{x ^{2} - x - 2}

x - 2 sin (x)
