domain of f(x)=x^2-9x-36

domain

f (x) = x^{2} - 9 x - 36

- \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

7 x + 4

f (x) = x (6 - x)

f (x) = 1 - 2^{x - 2}

f (x) = x^{2} \cdot e^{- x}

x + 6 + 3
