domain of x^2+x-20

domain

x^{2} + 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

e x t re m e f (x) = 3 x - 3

r an g e f (x) = (x - 3)^{2} + 5

cr i t i c a l f (x) = 3 x^{4} + 4 x^{3}

r an g e f (x) = lo g_{\frac{1}{20}} (- x)

a sy m pt o t es f (x) = \frac{6}{x - 5}
