Identify Function & Point: Identify the function and the point at which we need to find the derivative. The function given is h(x)=x−5, and we need to find the derivative of h at x=2, denoted as h′(2).
Differentiate with Respect: Differentiate the function h(x) with respect to x. The derivative of xn with respect to x is n⋅x(n−1). Therefore, the derivative of h(x)=x−5 is h′(x)=−5⋅x(−5−1)=−5⋅x−6.
Substitute x=2: Substitute x=2 into the derivative to find h′(2).h′(2)=−5⋅(2)−6=−5/(26).
Calculate h′(2): Calculate the value of h′(2).26=64, so h′(2)=−645.
