Find the derivative of f(x) = x^2(x - 5)^3

Solution

PIL import Image import pytesseract

Load the uploaded image

image_path = "/mnt/data/1733605473758retbaokk.jpg" image = Image.open(image_path)

Use OCR to extract text from the image

extracted_text = pytesseract.image_to_string(image) extracted_textThe OCR extraction yielded incomplete or incorrect results. The function given in the image appears to be f(x)=x2(x5)3f(x) = x^2 (x - 5)^3. I will proceed to compute its derivative.

Derivative of f(x)=x2(x5)3f(x) = x^2 (x - 5)^3

We apply the product rule and chain rule: f(x)=uvwhere u=x2 and v=(x5)3f(x) = u \cdot v \quad \text{where } u = x^2 \text{ and } v = (x - 5)^3

  1. Derivative of u=x2u = x^2: u=2xu' = 2x

  2. Derivative of v=(x5)3v = (x - 5)^3 using the chain rule: v=3(x5)21=3(x5)2v' = 3(x - 5)^2 \cdot 1 = 3(x - 5)^2

Using the product rule: f(x)=uv+uv=(2x)(x5)3+(x2)(3(x5)2)f'(x) = u'v + uv' = (2x)(x - 5)^3 + (x^2)(3(x - 5)^2)

Simplify: f(x)=2x(x5)3+3x2(x5)2f'(x) = 2x(x - 5)^3 + 3x^2(x - 5)^2

Factor common terms x(x5)2x(x - 5)^2: f(x)=x(x5)2[2(x5)+3x]f'(x) = x(x - 5)^2 \left[ 2(x - 5) + 3x \right]

Simplify the bracket: 2(x5)+3x=2x10+3x=5x102(x - 5) + 3x = 2x - 10 + 3x = 5x - 10

Final derivative: f(x)=x(x5)2(5x10)f'(x) = x(x - 5)^2 (5x - 10)
