Part B

See solution    for AB/BC   3,  Review  for Chapter 3.

(a) Using   the differential    equation,   evaluate    the derivative  at  each
point, then sketch a short segment having that slope. For example, at
; draw a segment at (−1, −1) that
decreases steeply. Repeat this process at each of the other points.
The result is shown below.

Move    to  (0.5    +   0.5,    −1  +   1)  =   (1, 0), then    f(1)    ≈   0.
The differential equation is separable:

It  is  given   that    f   passes  through (0,−1), so  −1  =   tan(0^2     +   c)  and 
.
The solution is .
