Alexis created a function table using the equation y=x+ 3.<br>Which table is correct?​
aev [14]

The correct answer is B (Green table)

Explanation:

In mathematics, a function table shows different values for Y and X that are part of a mathematical function. Additionally, for the table to be correct the mathematical function or equation needs to be valid in each of the rows.

According to this, in the equation presented the value of x added to 3 should be equal to the value shown for y as x+3= y. This occurs only in the green table; for example, the first value for x is 1 and for y is 3, this makes the equation valid 1 (x) + 3 = 4. Also, in the last row, the value of x is 11 and the value of y is 3, which also matches the equation 11 (x) + 3 = 14 (y).
