domain of x^4+1

domain

x^{4} + 1

- \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) = 2 x + 5 y = 10

(- 1, - 6), (4, 5)

(- 2, 2), (3, 4)

f (x) = - 7 x (x - 5) (x - 7)

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