Given ƒ(x) = 2/3x - 1, complete parts a and b. part a: using the table provided, create five points to demonstrate that for the function, ƒ(x) = 2/3x - 1, there is exactly one output value for each corresponding input value. in your final answer, include all calculations and the completed table. x y part b: on a separate sheet of paper, use the points created in part a to graph the function, ƒ(x) = 2/3x - 1. label the values on the x- and y-axes, and all points on the graph.
