Differentiate function h(x): Differentiate the function h(x)=x61 with respect to x. To differentiate h(x), we use the power rule for derivatives, which states that the derivative of xn with respect to x is n⋅x(n−1). In this case, we can rewrite h(x) as x−6 and then apply the power rule. h′(x)=dxd[x−6]h(x)=x610h(x)=x611
Apply power rule: Evaluate the derivative at x=1. We substitute x=1 into the derivative we found in Step 1. h′(1)=−6⋅1−7h′(1)=−6⋅1−7 Since any number to the power of −7 is just its reciprocal raised to the 7th power, and the reciprocal of 1 is still 1, we have: h′(1)=−6⋅(1)h′(1)=−6
