Answer:
Part A)
Part B)
Step-by-step explanation:
We have the equation:
Part A)
We want to find the derivative of our function, dy/dx.
So, we will take the derivative of both sides with respect to <em>x:</em>
<em /><em />
The derivative of a constant is 0. We can expand the left:
Differentiate using the product rule:
Implicitly differentiate:
Rearrange:
Isolate the dy/dx:
Hence, our derivative is:
Part B)
We want to find the equation of the tangent line at (2, 1).
So, let's find the slope of the tangent line using the derivative. Substitute:
Evaluate:
Then by the point-slope form:
Yields:
Distribute:
Hence, our equation is:
Answer:
Mid- point =(-4+2/2, -2+8/2)
=(-2/2,6/2)
=(-1,3)
