Answer: SECOND OPTION
Step-by-step explanation:
By definition the domain is the set of value of the input (x values) shown in the table attached in the problem.
By definition the domain is the set of value of the output (y values) shown in the table attached in the problem.
Therefore, keeping the above on mind, you have:
Domain:{-2,-1,0,1,2,3}
Range:{-8,-1,0,1,8,27}
Answer:
(-3,2)

Answer:
The constant of variation is $1.50
Step-by-step explanation:
Given
Point 1 (1,2)
Point 2 (5,8)
Required
Constant of Variation
Though the graph would have assisted in answering the question; its unavailability doesn't mean the question cannot be solved.
Having said that,
the constant variation can be solved by calculating the gradient of the graph;
The gradient is often represented by m and is calculated as thus
Where
By substituting values for x1,x2,y1 and y2; the gradient becomes
Hence, the constant of variation is $1.50
