Question
How do I solve?
![**Problem Statement: Graph Transformation**
Given:
Let \( f(x) = 4\sqrt{x} \).
**Task:**
If \( g(x) \) is the graph of \( f(x) \) shifted down 6 units and left 1 unit, write a formula for \( g(x) \).
**Solution:**
- The transformation of a function \( f(x) \) by shifting it horizontally to the left by \( h \) units is given by \( f(x + h) \).
- Vertically shifting the graph down by \( k \) units is achieved by subtracting \( k \) from the function, resulting in \( f(x) - k \).
**Applying the transformations:**
1. Shift left by 1 unit: Replace \( x \) with \( x + 1 \) in \( f(x) \).
\[
f(x+1) = 4\sqrt{x+1}
\]
2. Shift down by 6 units: Subtract 6 from the function.
\[
g(x) = 4\sqrt{x+1} - 6
\]
Thus, the formula for \( g(x) \) is:
\[
g(x) = 4\sqrt{x+1} - 6
\]
**Instructions:**
- Enter \( \sqrt{x} \) as `sqrt(x)`.

Step 1
Given that, the graph of the function is and also given that, the function shifted down 6 units and left 1 unit.
"Vertical Shifts:
If c is a positive real number, the graph of the graph of shifted upward c units.
If c is a positive real number, the graph of the graph of shifted downward c units.
Horizontal Shift:
If c is a positive real number, then the graph of is the graph of shifted to the right c units.
If c is a positive real number, then the graph of is the graph of shifted to the left c units.."
