To find the vertex of the quadratic function f(x) = -2x² + 12x - 14, we can use the vertex formula. In this case, the quadratic function is in the form f(x) = ax² + bx + c, with a = -2, b = 12, and c = -14.

The x-coordinate of the vertex is given by x = -b / (2a). Plugging in the values, we get:

x = -12 / (2 * -2)
  = -12 / -4
  = 3

So, the x-coordinate of the vertex is x = 3. To find the ...
