domain of f(x)=x^2+19x-18

domain

f (x) = x^{2} + 19 x - 18

- \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 (t) = ∣ t - 1 ∣ + ∣ t - 3 ∣

y = (x^{2} + x + 4) 3 x - 2 x + 7

f (x) = 1 - x^{2} - x^{3} + 2 x^{7}

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

f (x) = 45 x^{2}

What is the domain of f(x)=x^2+19x-18 ?
The domain of f(x)=x^2+19x-18 is -infinity <x<infinity
