URGENT!!!!!!!! how to find the limit of x---4 x3-64/x2-16 Share with your friends Share 0 Vipin Verma answered this limx→4x3-64x2-16Here if we put x =4 in the function , the function will get changed into 00 form.So we have to remove this 00 form by individually differentiating numerator and denominator w.r.t x.this is called L-hospital rule.hence limx→4x3-64x2-16=limx→4ddx(x3-64)ddx(x2-16)=limx→43x22x, hence 00form is removed. Putting x =4, we get the limit=3(4)22(4)=6 0 View Full Answer
