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

domain

f (x) = 3 x^{2} + 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

lo g_{10} (3 x + 6)

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

5 x + 15

1.2 x (\frac{700 - 66 x}{55.2})

+ \frac{x}{3} + 2
