To find: the rule that describes the order pairs
Answer to Problem 46STP
Option H describes the order pairs
Explanation of Solution
Given:
x | y |
1 | 1 |
2 | 4 |
3 | 7 |
4 | 10 |
F
H
G
J
Calculation:
Option F:
This relation is not valid for the above table, as it says that x and y are equal everywhere, but this doesn't hold.
As, when
Option G:
Substitute all values of x in the above equation to check if the value, of y thus obtained is same as that given in table or not.
At
Since the first value itself don't match, therefore this relation is also not valid.
Option H:
Substitute all values of x in the above equation to check if the value, of y thus obtained is same as that given in table or not.
At
At
At
At
Since the values obtained above are same as in table.
Thus our answer is H
Conclusion:
Thus, option H describes the order pairs
