domain of f(x)=7x^2+1

domain

f (x) = 7 x^{2} + 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

\frac{2}{3} tan (2 x + π)

\frac{x ^{3} - 6 x ^{2} + 4 x + 8}{x ^{3} - x ^{2} - 9 x + 9}

y = \frac{x ^{2} - x}{x ^{2} - 1}

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

f (x) = lo g_{10} (5) (3 x^{2} - 5 x + 2)

What is the domain of f(x)=7x^2+1 ?
The domain of f(x)=7x^2+1 is -infinity <x<infinity
