Rolle’s Theorem. Find the values of c that satisfy Rolle’s Theorem of y=-x^3+2x^2+x-6 [-1, 2]. We learn how to determine if Rolle’s Theorem can be applied to y=-x^3+2x^2+x-6 [-1, 2]. If it can, we find all values of c that satisfy the theorem. If it cannot, we explain why not. We learn how to apply Rolle’s Theorem to a function. We first determine if Rolle’s Theorem can be applied. If it can not be applied, we state why. If Rolle’s Theorem can be applied, we first take the derivative of the function. We then set the derivative equal to zero and solve for x. Once we get these values we determine which ones are within our bounds of the problem. These values are the values of c that satisfy Rolle’s Theorem. This is a great introduction into Rolle’s Theorem. This is under the topic of Applications of Differentiation with this free online math video lesson. #RollesTheorem #findthevalueofc #ApplyRollesTheorem #derivatives #Theorem #calculus #calculushelp #minutemath #minutemathhelp #onlinemathlessons
