Answer:
(-3, 4) is a solution
Step-by-step explanation:
The point (-3, 4) is inside the shaded area of the graph, so is a solution.
You can check in the inequality
y > -2x -3
4 > -2(-3) -3 . . . . substitute for x and y
4 > 3 . . . . . . . true; the given point is a solution
Use the remainder theorem: we can decompose the given polynomial in terms of quotient and remainder polynomials and
, respectively, such that
Then letting x = -3 makes the quotient term vanish, and we're left with a remainder of
