domain of f(x)=2x^2+4x-1

domain

f (x) = 2 x^{2} + 4 x - 1

- \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) = 2 x^{2} - 8 x + 5

f (x) = x^{2} - 5 x + 6

g (x) = 4^{x - 2}

y = \frac{x}{x - 1}

4 x^{2} + 17 x - 15
