Is relation t a function? is the inverse of relations t a function?

relation t

x 0 2 4 6
y -8 -7 -4 -4

a. relation t is not a function. the inverse of relation t is a function.

b. relation t is not a function. the inverse of relation t is a function.

c.
relation t is not a function. the inverse of relation t is not a function.

d.
relation t is a function. the inverse of relation t is not a functions.

All u need to do is look at the x valuesif there is no repeating x values, it is a function...does not matter if the y values repeat or not.

relation t : (0,-8)(2,-7)(4,-4)(6,-4)
since there is no repeating x values, this IS a function

inverse of relation t : switch ur x and y terms
(-8,0)(-7,2)(-4,4)(-4,6)
since there ARE repeating x values of -4, this is NOT a function

so relation t is a function and the inverse of relation t is not a functionanswer is D.

17 is c. congruent means equal in size

The answer is 63.!
