domain of f(x)=x^4+8x^2+16

domain

f (x) = x^{4} + 8 x^{2} + 16

- \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) = - e^{x + 7}

(- 3, - 5), (- 0.5, 0)

\frac{( x ^{2} - 5 )}{7 x ^{2}}

- \frac{9}{2 x ^{\frac{3}{2}}}

f (x) = - 10 lo g_{4} (x)
