Given that the point (9,7) is on the graph of y=f(x), there is one point that must be on the graph of 2y=f(2x)2+2. What is the sum of coordinates of that point?
The sum of the coordinates is 5 + (-7/2) = 3/2.
The answer is wrong but thanks for answering.
f(9)=7
f(2*4.5)=7
If x=4.5
then
2y=72+2y=114y=2.75
4.5+2.75 = 7.25
