SOLUTION: If the point P is on the graph of a function f, find the corresponding point on the graph of the given function. P(4,9) y=1/3f(1/2x)-1

Question 922083: If the point P is on the graph of a function f, find the corresponding point on the graph of the given function.
P(4,9) y=1/3f(1/2x)-1

P(4,9)

Since we know that P(4,9) is on the graph of y=f(x),
that means that f(4)=9

The equation above contains , 
and since we know that f(4)=9, then if 


then


Therefore substituting x=8 in the original equation,








So the corresponding point = (8,2)
