Use complete sentences to describe the relation in terms of a function. f = {(2, -4), (2, 7) (3, 5), (4, -1), (8, 7)}

The relation F is not a function

Step-by-step explanation:

A relation is a function if and only if for each input value x, there is a single output value y.

If for an input value x there are two or more output values y then the relation is not a function.

In this problem we have the following relationship:

F = {(2, -4), (2, 7) (3, 5), (4, -1), (8, 7)}

Note that for the input value there are two possible output values: ,  .

Therefore, based on the definition described above, the relation F is not a function

unless if u could do my questions, if not i wouldn't want to

the answer is a) y= 2 csc [0.5 (x+pi/2)]-1
