Unformatted text preview: and suppose that P ( t ) satisﬁes the diﬀerential equation P ( t ) = 0 . 453 P ( t ) . Find the formula for P ( t ) if initially there are approximately 10,500 bacteria present. 4. (15 points) f ( x ) = (4x ) e x . (a) f ( x ) = ? (b) f 00 ( x ) = ? (c) Find the x coordinate of each possible extremum. (d) Use f 00 ( x ) to say whether each answer in (c) is a relative maximum or minimum. 5. (15 points) f ( x ) = 6 x + ex . (a) f ( x ) = ?
