a. Compare the graphs of \(y=(x+1)(x+2)(x+3)\) and \(y=(x-1)(x-2)(x-3)\) . What transformation could you use to describe the change from one graph to the other? b. Compare the graphs of \(y=(x+1)(x+3)(x+7)\) and \(y=(x-1)(x-3)(x-7) .\) Does the transformation that you chose in part (a) still hold true? Explain. c. Make a Conjecture What transformation could you use to describe the effect of changing the signs of the zeros of a polynomial function?
