Math Problem Statement

Functions f and g are defined by: f(x) = 3x - 4, x ∈ R; g(x) = 2(x - 1)^3 + 8, x > 1. Tasks: (i) Evaluate f(g(2)). (ii) Sketch the graphs of y = f(x) and y = f^(-1)(x), showing their relationship. (iii) Obtain g'(x) and explain why g has an inverse. (iv) Express f^(-1)(x) and g^(-1)(x) in terms of x.

PIL import Image

Load the image to analyze its contents

image_path = '/mnt/data/1732723792433feo4iemq.jpg' image = Image.open(image_path) image.show()I have displayed the image. Let me now process its contents to extract any relevant mathematical information. I'll provide a detailed explanation pytesseract

Use pytesseract to extract text from the image

extracted_text = pytesseract.image_to_string(image)

extracted_textThe text extracted from the image contains a mathematical problem involving functions ff and gg. Here's the relevant content broken down:

  1. Functions Definition:

    • f(x)=3x+4f(x) = 3x + 4, for xRx \in \mathbb{R}
    • g(x)g(x) is defined as g(x)=13x+8g(x) = \frac{1}{3}x + 8
  2. Task (i): Evaluate f(g(2))f(g(2)).

  3. Task (ii): Sketch the graphs of y=f(x)y = f(x) and y=f1(x)y = f^{-1}(x), and explain the relationship between the two graphs.

  4. Task (iii): Obtain an expression for g(x)g(x) and explain why it has an inverse.

  5. Task (iv): Express both f1(x)f^{-1}(x) and g1(x)g^{-1}(x) in terms of xx.
