Final answer:
To find the inflection points of the function, you need to find where the second derivative equals zero. The second derivative of the function is f''(x) = 36 x³ - 54 x² - 82 x + 120. Newton's method can be used to approximate the roots of this equation, which will give the x-values of the inflection points.
Explanation:
To find the inflection points of the function f(x) = 9/5 x⁵ − 9/2 x⁴ − 41/3 x³ +60x²+1, we need to find where the second derivative of the function equals zero. This is because an inflection point is where the function changes from concave up to concave down or vice versa, which corresponds to the second derivative changing sign.
First, find the first derivative of f(x) which is f'(x) = 9 x⁴ − 18 x³ − 41 x² +120x. Then find the second derivative which is f''(x) = 36 x³ - 54 x² - 82 x + 120.
To find the roots of this equation we could use Newton's method. This iterative method starts with an initial guess for the root, then refines that guess using the formula x1 = x0 - f(x0)/f'(x0). Repeat this formula taking x1 as the new initial guess until you get to a desired level of precision.
Solving that with Newton's method might be challenging due to cubic equation characteristic but it's possible.
