Function Transformations 5B34Fb
1. The problem asks to identify the order of transformations applied to the function $f(x) = x^2$ to get $f(-x + 4) + 3$.
2. The original function is $f(x) = x^2$.
3. The transformed function is $f(-x + 4) + 3$.
4. Let's analyze the transformations inside the function first: $f(-x + 4)$.
5. Rewrite $-x + 4$ as $-(x - 4)$ to understand the transformations better.
6. The expression $f(-(x - 4))$ means:
- First, translate the input $x$ by 4 units to the right (because of $x - 4$ inside the function).
- Then reflect over the y-axis (because of the negative sign outside the parentheses).
7. After these inside transformations, the function becomes $f(-(x - 4)) = (-(x - 4))^2 = (x - 4)^2$ because squaring removes the negative sign.
8. Finally, the $+3$ outside the function means translate the entire graph up by 3 units.
9. So the order of transformations applied to $f(x) = x^2$ to get $f(-x + 4) + 3$ is:
- First: translate right 4 units (due to $x - 4$ inside the function)
- Second: reflect over the y-axis (due to the negative sign)
- Third: translate up 3 units (due to $+3$ outside the function)
10. However, the problem asks for the transformations in the order they occurred and gives options:
- Type 1: translate left 4 units
- Type 2: translate up 3 units
- Type 3: reflect over the y-axis
11. Since the function has $-x + 4$, rewriting as $-(x - 4)$ shows a translation right 4 units, but the problem only gives translate left 4 units as an option.
12. To match the problem's options, note that $f(-x + 4) = f(-(x - 4))$ is equivalent to reflecting over the y-axis first (change $x$ to $-x$), then translating left 4 units (because $-x + 4$ inside the function shifts the graph left by 4 units after reflection).
13. Therefore, the correct order of transformations is:
- First: reflect over the y-axis (Type 3)
- Second: translate left 4 units (Type 1)
- Third: translate up 3 units (Type 2)
Final answer:
First Transformation: 3
Second Transformation: 1
Third Transformation: 2
