+249 Hi, this is a repost but my question did not get answered and I would really like some help on it. :)
Given that the point (4,7) is on the graph of y=f(x), there is one point that must be on the graph of 2y=3f(4x)+5. What is the sum of coordinates of that point?

If x=1 then f(4x)=f(4)=7
so
2y=3*7+5
2y=26
y=13
So that one point could be (1,13)
I suppose the sum of the co-ordiantes is 1+13=14
It is a bit of a weird question but that is what I think ://
