domain of f(x)=5+x^2-4x

domain

f (x) = 5 + x^{2} - 4 x

- \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

\frac{2 x}{3 x - 8}

f (x) = e^{x} (x^{2} + x) x - sin (x)

f (x) = 2 x^{2} + 6 x + 10

f (x) = \frac{x}{4 x - 3}

f (x) = 3 - 2 x^{5}
