To be a function, a single value in the Domain can not map into multiple values in the Range.
the Domain is <span>{0}</span> and
the Range is <span>{3,2,1}</span>
This is not a function.
One solution
11x + 25 = 7x+15
-7x -7x
4x+25=15
-25 -25
4x= -10

x= -10/4
-10/4 simplified is -5/2
so there is one solution where x=-5/2
It’s 14.
The five numbers will be: 12, 13, 14, 15, and 17 so 14 is the median.
Horizontal line is y=, because every point along that horizontal line will have the same y value. So, now look at the point and notice that the y value is 5. So the horizontal line with a y value of 5 is y=5. Thus the answer is f.
