domain of f(x)=x^2-8x+40

domain

f (x) = x^{2} - 8 x + 40

- \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} - 64

f (t) = ln (9 - t^{2})

f (x) = x^{2} - 8 x + 10

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

\frac{1 - 6 x}{3 + x}
