Math Problem Statement
Solution
The task is to determine graphically the value of from the given curve, which appears to represent a function , along with a tangent line at the point on the curve where .
To solve this:
-
Tangent line at : represents the derivative of the function at . The derivative at this point is equal to the slope of the tangent line drawn at on the curve.
-
Slope of the tangent line: The blue line shown passing through point is the tangent line at . To calculate the slope of this line, we need to determine the rise over the run, or the change in -coordinates divided by the change in -coordinates between two points on this tangent line.
From the graph:
- One point on the tangent line is (since lies on the curve at ).
- Another visible point on the tangent line is approximately .
The slope of the tangent line can be calculated using:
Conclusion:
The value of , which is the slope of the tangent line at , is .
