domain of f(x)=(x^2+2)/8

domain

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

- \infty < x < \infty

Solution steps

The function has no undefined points nor domain constraints. Therefore, the domain is

- \infty < x < \infty

f (x) = e^{x^{2} - 1}

9 x^{4} - 36 x^{3} + 20 x^{2} + 32 x - 33

(8, 4), (22, 5)

\frac{4 x - 20}{x ^{2} - 2 x - 15}

\frac{( x - 8 )}{( x - 1 ) ( x + 2 )}

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