Question

What is the function rule shown by the table?

A. y = x - 1
B. y = x + 2
C. y = 2x + 1

Answer 1

The correct answer is C

Explanation:

If you take any number from the x column and multiply it by the number 2, then add 1 to the product, you will get the number in the y column as an answer.

For example, the number -2 from the x column multiplied by 2 equals -4, then add 1 to then number -4 and that equals -3.
