Math question: Find the vertex of the parabola represented by the function 𝑦 = -2𝑥^2 + 4𝑥 + 1.Answer: The vertex of the parabola is found using the formula 𝑥 = -𝑏/2𝑎. Substituting the coefficients, we obtain 𝑥 = -4/(2*-2) = 1. Plugging this x-value into the equation, we find the y-coordinate: 𝑦 = -2(1)^2 + 4(1) + 1 = 3. Therefore, the vertex is (1, 3). The
