Given information
Given that the equations are and . In the graph
Step-by-step explanation
Step 1.
We need to find , where
Applying The Quotient Rule:
If and are differentiable, then
since $f$ and $g$ are differentiable, we obtain
Observing the graph, we see that at .
For and , we need to find the slope of the line that goes through :
Substituting the obtained values, follows
