domain of f(x)=-log_{2}(x+2)

domain

f (x) = - lo g_{2} (x + 2)

x > - 2

Interval Notation

(- 2, \infty)

Solution steps

Find positive values for logs:

x > - 2

The function domain

x > - 2

f (x) = \frac{x ^{2} + x}{x ^{3} - 9 x}

y = 4^{x} - 3 \cdot 2^{x} + 2

f (x) = - \frac{1}{2} (4^{2 (x + 1)}) - 3

f (x) = - x^{3} - 2 x^{2} + 36 x + 72

- sin (x)

What is the domain of f(x)=-log_{2}(x+2) ?
The domain of f(x)=-log_{2}(x+2) is x>-2
