domain of 1+8x-2x^3

domain

1 + 8 x - 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

am pl i t u d e - 5 sin (2 x + \frac{π}{2})

d o main f (x) = \frac{x - 3}{x - 5}

cr i t i c a l f (x) = \frac{x}{( x ^{2} + 1 ) ^{2}}

d o main f (x) = x^{2} - 2 x^{3}

in t erce pt s f (x) = - x^{2} + 10 x - 21
