domain of f(x)=ln(x)(49-x^2)

domain

f (x) = ln (x) (49 - x^{2})

x > 0

Interval Notation

(0, \infty)

Solution steps

Find positive values for logs:

x > 0

The function domain

x > 0

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

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

\frac{x ^{2} + 2}{3}

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

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