Identify Function: Identify the function to differentiate.We are given the function f(x)=x71, which we need to differentiate with respect to x.
Apply Power Rule: Apply the power rule for differentiation. The power rule states that the derivative of xn with respect to x is n∗x(n−1). In this case, we can rewrite the function as f(x)=x−7 to apply the power rule.
Differentiate Using Rule: Differentiate using the power rule.Taking the derivative of f(x)=x−7 with respect to x, we get f′(x)=−7⋅x−7−1=−7⋅x−8.
Simplify Expression: Simplify the expression.The derivative f′(x)=−7x−8 can be rewritten as f′(x)=−x87 for clarity.
