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

domain

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

- \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{x}{x ^{2} - 9}

f (x) = \frac{3 x + 5}{7 - 6 x}

f (x) = 15000 + 1.5 x

f (x) = 96 x^{4} - 3 x

y = x + 4
