domain of f(x)=3x^2+8x-1

domain

f (x) = 3 x^{2} + 8 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) = \frac{x + 6}{( x - 6 ) ( x - 1 )}

2 x + 3, - 2 \leq x < 1

f (x) = ln (7 + 6 x - x^{2})

f (x) = \frac{2 x}{5 - 2 x}
