Question

Найдите область определения функции y= $frac{ln^2(x^2-3x)}{ sqrt{5x+1} }$

Answer 1

$OOF;; left { {{x^2-3x>0} atop {5x+1>0}} right. ; left { {{x(x-3)>0} atop {x>-frac{1}{5}}} right. ; left { {{xin(-infty,0)U(3,+infty)} atop {xin (-frac{1}{5},+infty)}} right. \\xin (-frac{1}{5},0)U(3,+infty)$
