  vertex: (-2, 4)

Step-by-step explanation:

Use your regression calculator to find the parameters of the quadratic model.

The vertex form equation is ...

  y = -3(x +2)^2 +4

so the vertex is (-2, 4).

__

The standard form equation is the expansion of the above:

  y = -3x^2 -12x -8

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )
