1. The problem asks to graph the function $f(x) = x$ after it has been vertically stretched by a factor of 2 and vertically shifted down by 3 units.
2. The original function is $f(x) = x$.
3. A vertical stretch by a factor of 2 means multiplying the function by 2: $$f(x) = 2x$$
4. A vertical shift down by 3 units means subtracting 3 from the function: $$f(x) = 2x - 3$$
5. So the transformed function is $$f(x) = 2x - 3$$.
6. This is a linear function with slope 2 and y-intercept -3.
7. To graph it, plot points such as:
- When $x=0$, $f(0) = 2(0) - 3 = -3$
- When $x=1$, $f(1) = 2(1) - 3 = -1$
- When $x=2$, $f(2) = 2(2) - 3 = 1$
8. The graph is a straight line passing through these points.
Final answer: The function after transformation is $$f(x) = 2x - 3$$.
