Afunction is defined as {(0,1), (2,3), (5,8), (7,2)}. issac is asked to created one more ordered pair for the function. which ordered pair can be add to the set to keep it a function? (0,2) (5,3) (7,0) (1,3)

A function is  a relation that maps to each input value exactly one output value.

Given the function as {(0,1), (2,3), (5,8), (7,2)}, you can rewrite it

f(0)=1;f(2)=3;f(5)=8;f(7)=2.

Now consider all options:

the ordered pair (0,2) cannot be add to this function, because then f(0)=2, but you have already that f(0)=1 and output value should be one value;the ordered pair (5,3) cannot be add  to this function, because then f(5)=3, but f(5)=8 (given) and output value should be one;the ordered pair (7,0) cannot be add to this function, because then f(7)=0, but f(7)=2;the ordered pair (1,3) can be add to the set, because f(1)=3 is unique ordered pair (with 1st coordinate 1)

correct option D

What is the rest of the question?
