Rewrite function: We are asked to find the derivative of the function f(x)=x121 with respect to x. To do this, we will use the power rule for differentiation, which 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−12 to apply the power rule.
Apply power rule: Applying the power rule, we differentiate x−12 with respect to x. According to the power rule, the derivative of xn is n∗xn−1. Therefore, the derivative of x−12 is −12∗x−12−1 or −12∗x−13.
Rewrite derivative: We can rewrite the derivative in a more conventional form by moving the negative exponent back to the denominator. So, the derivative −12x−13 becomes −x1312.
Final answer: We have found the derivative of the function (1)/(x12) with respect to x, which is −12/(x13). This is the final answer.
