Hello,jwebb19!

We have: .1) Find all values of where the tangent lines to and are parallel.

Since the slopes are equal: .

Therefore: .

. . . The point is: .2) Find an equation for the line tangent to the graph of at the point

The slope is: .

When , we have: .

The equation is: .

Therefore: .

3) Calculate .for

where (with a,b,c,d constant)
