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 and determine the order of its derivatives , , , and .
Steps:
-
Understand :
The derivative represents the slope of the tangent line to the graph of at point . -
Identify key points on the graph:
- : The slope is very negative because the graph is steeply decreasing. is a large negative value.
- : This is a local minimum. At local extrema (minimum or maximum), the slope is zero. Hence, .
- : The graph is increasing steeply, so the slope is positive.
- : The graph is flatter and decreasing, so is negative, but not as steep as at .
Compare the slopes:
- : Large negative value (very steep downwards).
- : Negative value, but smaller in magnitude than .
- : Zero (flat tangent at the local minimum).
- : Positive slope (increasing steeply).
Order the values in increasing order:
From most negative to most positive: Thus, the order is A, C, D, B.
