domain of f(x)=f(x)=ln(25-x^2)

domain

f (x) = f (x) = ln (25 - x^{2})

- 5 < x < 5

Interval Notation

(- 5, 5)

Solution steps

Find positive values for logs:

- 5 < x < 5

The function domain

- 5 < x < 5

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

f (x) = 2 x - x^{3}

f (x) = lo g_{10} (\frac{3 + x}{3 - x})

\frac{1}{x ( x ^{2} - 49 )}

\frac{2 x ^{2} - 7 x - 16}{( x + 4 ) ( x - 4 ) ( x - 7 )}

What is the domain of f(x)=f(x)=ln(25-x^2) ?
The domain of f(x)=f(x)=ln(25-x^2) is -5<x<5
