7. Не выполняя построение, найдите координаты точек пересечения графиков функций у = 18/x и у = x + 3

Set 18/x = x + 3. This leads to x² + 3x - 18 = 0. Factoring gives (x + 6)(x - 3) = 0. The x-coordinates are -6 and 3. Substituting back into y = x + 3 gives y = -3 and y = 6. The intersection points are (-6, -3) and (3, 6).
