10. Write a rule for the funtion represented by the table
--------------------------------
l x l y l
--------------------------------
l o l 9 l
--------------------------------
l 1 l 28 l
-------------------------------
l 2 l 47 l
-------------------------------
l 3 l 66 l
-------------------------------
+ y = 9 + 19x
o y = 18 + 10x
o y = 19 + 9x
o y = 10 + 18x
Is it a, y = 9 + 19x?
yes
Yes, the correct rule for the function represented by the table is y = 9 + 19x.
To determine the correct rule for the function represented by the table, we need to analyze the given values of x and y.
Looking at the table, we can see a pattern in the values of y when x increases by 1. For each increase in x by 1, y increases by 19 units. This pattern suggests that the rule for the function is that y is equal to 19 multiplied by x, plus an initial value.
To find this initial value, we can observe that when x is 0 (represented by the entry 'o' in the table), y is 9. Therefore, the initial value can be deduced as 9.
Hence, the correct rule for the function is y = 9 + 19x.
Therefore, the answer is indeed a, y = 9 + 19x.
