domain of f(x)=3+6x-8x^2

domain

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

- \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 + 1 - 4

(5 x - 6) (2 x^{2})

f (x) = \frac{3 x ^{2} + 6 x + 9}{x ^{2} + 4 x + 3}

f (x) = \frac{( 11 )}{x - 4}

y = \frac{4}{x ^{2} + 4} + \frac{7}{x ^{2} - 9}

What is the domain of f(x)=3+6x-8x^2 ?
The domain of f(x)=3+6x-8x^2 is -infinity <x<infinity
