Use first principle to find y'all for y=xe^x

By definition of the derivative,

We can employ the standard manipulation for proving the product rule:

The remaining limit is pretty well-known and has a value of 1. We can derive it from the definition of ,

In the limit above, we substitute , so that . As , we have :

After all this, we've shown that

the area of the rectangle is 35units^2.

step-by-step explanation:

graph it and find the distance.

it is a 5*7 rectangle.

therefore the area is 35units^2.

b. b < 1 might be the correct answer
