How do I solve this for a given stock...on excel

Highlight the abbreviated forecast of the next five-year DCF or FCFF forecasts (i.e., year by year) and the normalized, constant growth calculation for forecast years 6 to infinity.

Provide a DCF or FCFF model-based valuation range, explaining in brief your inputs. This range will serve as an absolute valuation metric and will be calculated by discounting your individual five-year FCFF forecasts by a realistic WACC, discounting the constant growth by the WACC, subtracting out debt, and dividing by shares outstanding. Highlight this absolute valuation range.
