My plot is off. I believe the plot should start from 0-1, however, I'm stuck.

Express the following model in a form used for defining the efficiency frontier using 3. the weighting method and the constraint method. Maximize z, = 4x x Maximize z: = 2x1 +6x2 Subject to x, 20 Define (plot) the efficiency frontiers in decision and objective spaces.
