FUNÇÃO DO 2º GRAU | Valor Máximo da Parábola

📚 In this math lesson, we'll solve a complete problem about quadratic functions involving the maximum value of the parabola, the discriminant (Δ), and the coefficient of the function. The problem deals with the function: f(x) = a(x−1)(x−9) and asks for the value of the coefficient "a" knowing that the maximum value of the function is 80. 📌 Topics covered: ✔ How to develop a quadratic function ✔ How to calculate the discriminant (Δ) ✔ Formula for the vertex of the parabola ✔ Maximum and minimum value of the function 👍 Like this video to support the channel 📌 Subscribe to the channel for more math content 💬 Comment with your questions or suggestions for future videos #mathematics #teacher #enem #school #learnmathematics #mathematicslesson #matematika
