X=-2
Explanation is I just know the answer
Simplify
The Domain is set of all real numbers
If 40% reps 98
100% will rep (98/50)*100 = 245
In this relation we have two ordered pairs:
( 5, 7 ) and ( 5, 8 )
For x = 5 : f ( x ) = 7 and also for x = 5, f ( x ) = 8. This is not possible for a function.
Answer:
b ) No. The relation is not a function.
If your looking for the value of "x" it is 4.
Hope this helped!
