Answer:
1:4
Step-by-step explanation:
For 26
ST is = TU
27
2x-1=15
2x=16
X=8
You just need to solve for when 
:
where 
is any integer. We only care about when 
, which happens for 
.
The relation t relates x to y. To determine if it is a function, see if one x value can give two different y values. Since each x value only has one y value, the relation is a function. To check if the inverse is a function, see if any one y value will give multiple x values. By inversing t, there are two values of x for the value of y = -4 (x = 4 and x = 6), so this is NOT a function.
Answer: Relation t is a function. The inverse of relation t is NOT a function.
