domain of x^2-8x+9

domain

x^{2} - 8 x + 9

- \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{25}{x ^{2}}

f (x) = \frac{5 x ^{6} - 8}{3 x ^{6} - 11 x ^{2}}

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

(- 1.2) (4)

m = 3, (2, 3)
