Answer:
a) Commutative property of addition
b) Identity Property of Multiplication
c) Identity Property of Addition
d) Associative Property of Addition.
Step-by-step explanation:
Hello,
1: dom f=R
2: img f =R
3: 2x²-x-6=2(x²-2x/4+1/46)-6-1/8=2(x-1/4)²-49/8
Vertex=(1/4,-49,8)
4: roots are -3/2 and 2
2(x-1/4)²-49/8=1/8[(4x-1)²-49]=1/8*(4x+6)(4x-8)
5:
From the vertex to ∞
[-1/4 , ∞)
<h3><em>This is the range of y , Ry=R−{0}</em></h3>
