Math Problem Statement

For the function g whose graph is given below, arrange the following values in increasing order: g'(-2), g'(0), g'(2), g'(4).

Solution

To solve this problem, we need to analyze the graph of the function gg and determine the order of its derivatives g(2)g'(-2), g(0)g'(0), g(2)g'(2), and g(4)g'(4).


Steps:

  1. Understand g(x)g'(x):
    The derivative g(x)g'(x) represents the slope of the tangent line to the graph of g(x)g(x) at point xx.

  2. Identify key points on the graph:

    • x=2x = -2: The slope is very negative because the graph is steeply decreasing. g(2)g'(-2) is a large negative value.
    • x=0x = 0: This is a local minimum. At local extrema (minimum or maximum), the slope g(x)g'(x) is zero. Hence, g(0)=0g'(0) = 0.
    • x=2x = 2: The graph is increasing steeply, so the slope g(2)g'(2) is positive.
    • x=4x = 4: The graph is flatter and decreasing, so g(4)g'(4) is negative, but not as steep as at x=2x = -2.

Compare the slopes:

  • g(2)g'(-2): Large negative value (very steep downwards).
  • g(4)g'(4): Negative value, but smaller in magnitude than g(2)g'(-2).
  • g(0)g'(0): Zero (flat tangent at the local minimum).
  • g(2)g'(2): Positive slope (increasing steeply).

Order the values in increasing order:

From most negative to most positive: g(2)<g(4)<g(0)<g(2)g'(-2) < g'(4) < g'(0) < g'(2) Thus, the order is A, C, D, B.


Final Answer:

A, C, D, B\textbf{A, C, D, B}
