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