domain of f(x)=8x^2+1

domain

f (x) = 8 x^{2} + 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

x^{2} - 6 x + 8

f (x) = \frac{x}{x - 9}

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

y = - x^{2} + 4 x

f (x) = 2 x^{3} + 3 x^{2} - 12 x
