Answer
### \( f(x) = -4^{2(x-3)} r + 5 \)
Explanation
## Step 1: Vertical Reflection### Reflecting the graph vertically involves multiplying the function by
. Thus, the function becomes \(f(x) = -4^x r\).## Step 2: Horizontal Compression### A horizontal compression by a factor of 2 is achieved by replacing
with
. The function becomes \(f(x) = -4^{2x} r\).## Step 3: Horizontal Translation### Translating the graph 3 units to the right involves replacing
with
. The function becomes \(f(x) = -4^{2(x-3)} r\).## Step 4: Vertical Translation### Translating the graph 5 units up involves adding 5 to the function. The final transformed function is \(f(x) = -4^{2(x-3)} r + 5\).
