1. Differentiate the function with respect to x. Explain your answer in a sentence by quoting a
relevant theorem. When in doubt, sketch a graph of a given function.
(a) 153.88
Solution. Since the derivative of a constant is 0,
(153.88) = 0.
(b) x
Solution

1. Differentiate. (x4 3x)ex
Solution. We apply the Product Rule:
[(x4 3x)ex ] = (x4 3x) ex + (x4 3x)(ex )
2. Differentiate.
= (4x3 3)ex + (x4 3x)ex = x4 + 4x3 3x 3)ex .
3x x2
Solution. Note that it is tempting to apply the Product Rule which is correct. H
