Math Problem Statement
Solution
We are given that , and we need to find , which is the derivative of evaluated at .
Using basic differentiation rules, we know:
Thus, to find , we need to compute .
Steps:
- From the graph, we will estimate the slopes (derivatives) and at .
- We will multiply by 4, then subtract from it to get .
Looking at the graph:
-
For : The graph of appears to be a straight line at , and the slope is the change in over the change in . By estimation from the graph, we see that for , the slope appears to be negative. A rough estimate gives .
-
For : Similarly, for , the slope at also looks negative but steeper than . A rough estimate gives .
Now substitute these estimates into the equation for :
So, .
