The pattern in the table is that x is increasing by 1 and y is increasing by a consistent amount. This suggests a linear function.
Looking at the values of y, we can see that they are being generated by adding a constant number to x. This constant number can be determined by looking at the difference between consecutive y values:
y2 - y1 = 3 - 0 = 3
y3 - y2 = 7 - 3 = 4
y4 - y3 = 11 - 7 = 4
y5 - y4 = 15 - 11 = 4
So the constant increase in y is 4. The equation for this function is y = 4x.
Therefore, 4 / 15 matches the function described in the table.
x / y
0 / -1
1 / 3
2 / 7
3 / 11
4/ 15
which equation matches the function described in the table?
