Show that the function š¶(š‘”) is strictly increasing in the interval (3, 4).Given. Equates the derivative C′(š‘”) to 0 and factorises C′(š‘”) as 3(3 + t)(6 āˆ’ t). Writes that for t ϵ (3, 4), 3>0, (3+š‘”)>0 and (6+š‘”)>0 Therefore, C′(š‘”)>0 Concludes that C(š‘”) is strictly increasing in the interval (3, 4).
