domain of x^2+7,x>=-5

domain

x^{2} + 7, x \geq - 5

x \geq - 5

Interval Notation

[- 5, \infty)

Solution steps

Set the domain to the given interval

x \geq - 5

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

x \geq - 5

\frac{2 x - 6}{x ^{2} - 6 x}

f (x) = 30 - 6 x

f (x) = \frac{ln ( 2 + x )}{x}

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

- 3 x - 5
