domain of f(x)=(sqrt(2x+4))/(x^4+81)

domain

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

x \geq - 2

Interval Notation

[- 2, \infty)

Solution steps

Find non-negative values for radicals:

x \geq - 2

The function domain

x \geq - 2

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

3 5 - x - 8

\frac{( ln ( x - 2 ) - 2 )}{4}

3 x (x - 1) (x + 2)

f (x) = x^{2} + 2 x + 1 g (x) = x - 1
