Turning Points Transformed
1. **Stating the problem:** We are given a function $y=f(x)$ with one turning point at $(-6,-4)$. We need to find the coordinates of the turning point for the transformed functions:
(a)(i) $y=f(x)+5$
(a)(ii) $y=f(3x)$
2. **Understanding turning points:** A turning point occurs where the derivative of the function equals zero (critical point) and the function changes direction.
3. **For part (a)(i):**
- The transformation is $y = f(x) + 5$, which shifts the function vertically upwards by 5 units.
- The $x$-coordinate of turning points remains the same, but the $y$-coordinate increases by 5.
- Therefore, the turning point coordinates are:
$$(-6, -4 + 5) = (-6, 1)$$
4. **For part (a)(ii):**
- The transformation is $y = f(3x)$, which horizontally compresses the function by a factor of 3.
- The turning point's $x$ coordinate changes since the input to $f$ is multiplied by 3.
- If original turning point is at $x=-6$, then solving $3x = -6$ gives $x = -2$.
- The $y$ value is $f(3x) = f(-6)$, which is $-4$.
- Hence the turning point coordinates are:
$$(-2, -4)$$

5. **Summary of answers:**
(a)(i): $(-6, 1)$
(a)(ii): $(-2, -4)$
6. **Regarding part (b):**
- The user has asked about the piecewise linear graph $y = g(x)$ shown, but no explicit question was given.
- To help with part (b), please provide the exact question you want answered about $g(x)$.
