Find the axis of symmetry f(x) = 2x2 - 4x.

x=1

Step-by-step explanation:

The function graph is a parabola (branches pointing up). Vertex (1; -2). The graph is symmetrical about the x axis = 1

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
