solve the linear programming problem with the simplex method.
maximize: p=x+2y−z
subject to:
x+y+z≤6
2x−z≤3
x≥0,y≥0,z≥0

Need match the functions with correct transformation. f(x) = -3x f(x) = |x-1|+3 f(x) = √(x+3) 1/2x² f(x) = (x+1)²-3 4|x| 1. compress by a factor of 1/2 2. stretch by a factor of 4 3. shift to the left 3 4. shift to the left 1 5. shift up 3 6. reflection
