domain of x^2+8x-20

domain

x^{2} + 8 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

y = 3 x^{2} - 4

f (x) = - 42 + 2 x

y = 4 x^{2} - 9 x

f (x) = \frac{2 x - 5}{x ^{2} - 4}

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