1. Problem Description

The point (9,1)(-9, 1) lies on the graph of f(x)f(x). Given the transformation g(x)=2f(x)+3g(x) = 2f(-x) + 3, we need to find the corresponding point on the graph of g(x)g(x).

2. Solution Steps

Since the point (9,1)(-9, 1) is on the graph of f(x)f(x), we have f(9)=1f(-9) = 1.
We are given g(x)=2f(x)+3g(x) = 2f(-x) + 3. We want to find a value of xx such that x=9-x = -9, because we know the value of f(9)f(-9).
From x=9-x = -9, we have x=9x = 9.
Now we can find the corresponding yy value for g(x)g(x) by substituting x=9x = 9 into the equation for g(x)g(x):
g(9)=2f(9)+3g(9) = 2f(-9) + 3.
Since f(9)=1f(-9) = 1, we have
g(9)=2(1)+3=2+3=5g(9) = 2(1) + 3 = 2 + 3 = 5.
Therefore, the corresponding point on the graph of g(x)g(x) is (9,5)(9, 5).

3. Final Answer

(9, 5)
