Точка пересечения с осью абсцисс-когда y равен нулю.
0=-3х+12 3х=12 х=4
Ответ:
√14-√13 > √15-√14
Объяснение:
√14-√13 √15-√14
прибавим к обеим частям √13+√14
√14-√13 +√13+√14 √15-√14 +√13+√14
2√14 √13+√15
возведем в квадрат
4*14 13+15+2√(13*15)
2*28 28+2√(13*15)
отнимем 28
28 2√(13*15)
14 √(13*15)
возведем в квадрат
196 195
196>195
значит: √14-√13 > √15-√14
