Math help will.give brainliest
Fofino [41]

Answer:

The point ( 0,-1) is a solution.

Step-by-step explanation:

y<= (x+1) (x+5)

y>= (x-1)^2 -6


See attached graph.


To prove algebraically, put the point (0,-1) into both equations and see if it is true for both of them.

y<= (x+1) (x+5)

-1 <= (0+1) (0+5)

-1<= 1*5

-1 <=5

True

y>= (x-1)^2 -6

-1 >= (-1)^2 -6

-1 >= 1-6

-1 >=-5

True

The point is a solution

Find the value of x in each quadrilateral.
patriot [66]
