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

domain

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

x > 0

Interval Notation

(0, \infty)

Solution steps

Find positive values for logs:

x > 0

The function domain

x > 0

f (x) = 4 x + 7

y = \frac{4}{x - 2}

f (x) = ln (10 x - 5)

- x^{2} + x + 12

f (x) = 20 x + 5

What is the domain of f(x)=2+log_{2}(x) ?
The domain of f(x)=2+log_{2}(x) is x>0
