a) Assume we had graph of sin(x^2 + 7x +5) conveniently available to us. If we shifted graph to right by 1 unit, what function would we be graphing?
b) Determine the symbolic expression for function, got from expression sin(x^2 + 7x +5).
c) The common incorrect answer to (b) is sin(x^2 +7x +4). Why is incorrect and what misunderstanding lies behind the mistake?
