Question

Write the inputs as an ordered pair so that it is not a function.

A. (5,0),(5,0),(2,6),(3,3)
B. (5,1),(5,1),(2,3),(3,6)
C. (5,25),(2,25),(3,9),(4,16)
D. (2,4),(3,9),(4,16),(5,25)

Answer 1

A. (5,0),(5,0) - this has repeated x-values with different y-values, violating the vertical line test for functions, so it is not a function.

B. (5,1),(5,1) - this has repeated x-values with different y-values, violating the vertical line test for functions, so it is not a function.

C. (5,25),(2,25) - this has repeated y-values with different x-values, violating the horizontal line test for functions, so it is not a function.

D. This set has distinct x-values with corresponding distinct y-values, so it is a function.

Answer 2

Step-by-step explanation: The not function is an excel logical function the function helps to check if one value is not equal to another, if we give true, it will return false, and then give false, it will return true, so, basically, it will always return a reverse logical value.
