QuestionResolva essas funções encontre as raízes da função do estudo da concavidade e o vértice da parábola 10:49 letra C) $2 x^{2}+5 x-3=0 \quad \Delta=b^{2}-4 a c$ 13:31

Studdy Solution
The vertex of the parabola is at $\left(-\frac{5}{4}, -\frac{49}{8}\right)$.
Solution: The roots of the quadratic equation $2x^2 + 5x - 3 = 0$ are $\frac{1}{2}$ and $-3$. The parabola is concave upwards. The vertex of the parabola is $\left(-\frac{5}{4}, -\frac{49}{8}\right)$.
