Question
Find the derivative of the following function.𝑓(𝑥)=−9𝑥3−𝑥𝑓′(𝑥)=
Solution
To find the derivative of the function f(x) = -9x^3 - x, we will use the power rule. The power rule states that the derivative of x^n, where n is any real number, is n*x^(n-1).
Step 1: Identify the terms in the function. Here we have two terms: -9x^3 and -x.
Step 2: Apply the power rule to each term.
