Which of the following relations represents a function? a. {(1, 1), (1, 2), (1, 3)} b. {(1, 1), (2, 1), (3, 1)} c. {(1, 1), (2, 2), (3, 3)} d. both b and c.

Remember ... A function relates an input to an output.It is like a machine that has an input and an output. And the output is related somehow to the input. So, I think it would be A) and C)

1/4 and 8/3 because:

the reciprocal if 4 is 1/4 because 4 is used as 4/1 and the opposite of that is 1/4. the opposite of 3/8 is 8/3 so that is the answer.

y = i/2 xtnop + (3i/2 tnop+ 1)
