Step 1:
From the table, the input or independent variable is x and the dependent variable is y.
Step 2:
From the table, to get the output, you multiply the input by 2.
When input is x = -3, the output y = -6, therefore. y = 2x = 2x(-3) = -6
When input is x = -2, the output y = -4, therefore. y = 2x = 2x(-2) = -4
When input is x = -1, the output y = -2, therefore. y = 2x = 2x(-1) = -2
When input is x = 0, the output y = 0, therefore. y = 2x = 2x(0) = 0
Ste 3: Final answer
The rule of the function is: y = 2x
f(x) = 2x Option D is the correct answer
