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 \(2y=\frac{f(2x)}{2}+2\). 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

\(2y=\frac{7}{2}+2\\ y=\frac{11}{4}\\ y=2.75\)

 

4.5+2.75 =  7.25
