domain of f(x)=2x^2+8x-5

domain

f (x) = 2 x^{2} + 8 x - 5

- \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) = 9 x + 2

f (x) = ln (\frac{4 x - 8}{2 x + 4})

f (x) = 2 x^{2} + 8 x + 1

f (x) = 2 x^{2} + 8 x + 5

\frac{1 0 ^{3 x}}{3}
