Answer:
It is Commutative
Step-by-step explanation:
An operation ∆ is said to be Commutative if a∆b=b∆a ∀ a,b ∈ ℝ.
Given the operation ∆ defined by:
a∆b=a X b

a∆b=
=3
Similarly, for the right hand side.

Therefore:
b∆a=
=3
These are the two ways of solving this problem and we have in fact shown that the operation is commutative as:
a∆b=b∆a=3
Answer:
graph 1= 3. graph 2= -3
Step-by-step explanation:
the y-intercept is where it cuts the line
therefore,
graph 1=3
graph 2=-3
This doesn't represent an function. Because the output is uneven to the other outputs,
1=4, 2=7 if you divided 2 into 2 parts it would equal 1=3.5 not 4.
Answer:
Y= x-7
