domain of f(x)=3x^4-7

domain

f (x) = 3 x^{4} - 7

- \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) = 6 x^{2} - 6

f (x) = \frac{x ^{2} - 3}{5 x ^{2} + 2 x + 1}

f (x) = \frac{2 x + 4}{x ^{4} + 81}

f (x) = \frac{4 x + 2}{x ^{2} + 7 x - 8}

3 5 - x - 8

What is the domain of f(x)=3x^4-7 ?
The domain of f(x)=3x^4-7 is -infinity <x<infinity
