Math Problem Statement
Solution
We are asked to arrange the following numbers in increasing order: , , , , and . From the given graph of the function , let's analyze the slopes (derivatives) at the specified points, as the slope of the tangent line at any point is the derivative .
Observing the graph:
- : The slope of the tangent line at appears to be zero, as the graph is flat at this point.
- : The slope at is positive, since the graph is increasing steeply around this point.
- : The slope at is also positive but less steep than at , so , but both are positive.
- : The slope at is negative, as the graph is decreasing steeply here.
Summary of slopes:
- (flat slope)
- (positive slope)
- (positive slope, less than at )
- (negative slope)
Ordering:
The negative slope at will be the smallest, followed by , then the positive slopes and , with being steeper than .
Thus, the correct increasing order is:

- How can we determine the concavity of the graph based on the second derivative ?
- What is the significance of a zero derivative at a point like ?
- How does the steepness of the graph relate to the magnitude of the derivative?
- What does it mean if the derivative changes sign between points?
- How can we estimate the exact value of the derivative from a graph?
Tip: The slope of the tangent line (derivative) at a point on a curve can give insight into whether the function is increasing, decreasing, or stationary at that point.
