Answer:
y≤x²+4x-1.
Step-by-step explanation:
1) to define the equation of the given graph; it is y=x²+4x-1 (its vertex is (-2;-5));
2) to define inequation accorging to the given graph (the area outside of the parabola means ≤).
Let 
. Then
Meanwhile, since
, you have 
.
It follows that
, 
, and 
, so that the quadratic fit for that satisfies the given points is
Note that this is just the second-order Taylor polynomial for
about 
.
