domain of 20x^3+30x^2-50x+20

domain

20 x^{3} + 30 x^{2} - 50 x + 20

- \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} - 6}{x - 4}

f (x) = - 2 x^{2} + 3 x - 5

y = \frac{2 x + 3}{x - 1}

f (x) = - x 4 - x^{2}

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