Question

The table and the graph show the relationship between the edge length, x, of a cube and its surface area, y. Is the relation a function?

Answer 1

no it is non- linear

Explanation:

Answer 2

Yes, the relationship between x and y is a non-linear function.

Explanation:

Given the table

Edge Length, x Surface Area, y

1 6

2 24

3 54

4 96

• The table values clearly represent a function, because each input value has one and only one output value. i.e. there is no repetition of x values.

• Also from the table values and the graph, it is clear that the function is not a linear function, because the graph is not a straight line. Also, In a cubic function, the highest power over the x variable(s) is 3. So, it is not a linear function.

Hence, we conclude that Yes, the relationship between x and y is a non-linear function.

Therefore, the 'last option' is correct.
