Question

A. Complete the table

B. Is the relationship a function? Explain.

Answer 1

Using the first answer, you can determine it is a function if it crosses the X axis

Answer 2

They tell you that the relationship is y is the product of x and 2. Product means the result of multiplication.

y=2x

And this is a function as each input value, x, has one unique output value, y.)

For output values you will get 2 times the input values. So for x={-2,-1,0,1} you get:

y={-4,-2,0,2}
