特定のドメインを念頭に置くことなく、連続関数の根の正確な数を見つけることはできません。たとえば、この場合、関数f（x）= sin（x） + x^2は、sin（x）とx^2の両方が無限に多いため、間隔（-∞、 +∞）に無限に多くの根を持っています。ルーツ。ただし、特定の間隔で正確な根の数を見つけることは困難な問題であり、連続関数のすべての根を見つける一般的な式はありません。
It's not possible to find the exact number of roots for a continuous function without having a specific domain in mind. For example, in this case, the function f(x) = sin(x) + x^2 has infinitely many roots in the interval (-∞, +∞), as both sin(x) and x^2 have infinitely many roots. However, finding the exact number of roots in a specific interval is a difficult problem, and there is no general formula to find all roots of a continuous function.
