We are given the transformed function $f(x) = -3h(x - 4) - 2$, and we need to determine the transformations applied to the parent function $h(x)$. We need to identify the reflections, stretches/compressions, vertical shifts, and horizontal shifts.

1. Problem Description

We are given the transformed function f(x)=3h(x4)2f(x) = -3h(x - 4) - 2, and we need to determine the transformations applied to the parent function h(x)h(x). We need to identify the reflections, stretches/compressions, vertical shifts, and horizontal shifts.

2. Solution Steps

The general transformation of a function h(x)h(x) can be represented as f(x)=ah(b(xc))+df(x) = a \cdot h(b(x - c)) + d.
Here, f(x)=3h(x4)2f(x) = -3h(x-4) - 2, so we have:
a=3a = -3
b=1b = 1
c=4c = 4
d=2d = -2
a) Reflections: The negative sign in front of 33 (i.e., a=3a = -3) indicates a reflection over the x-axis.
b) Stretches/Compressions: The absolute value of aa is 3=3|-3| = 3. Since a>1|a| > 1, there is a vertical stretch by a factor of 33. Since b=1b = 1, there is no horizontal stretch or compression.
c) Vertical Shifts: The term d=2d = -2 indicates a vertical shift downwards by 2 units.
d) Horizontal Shifts: The term xc=x4x - c = x - 4 indicates a horizontal shift to the right by 4 units.

3. Final Answer

a) Reflection over the x-axis.
b) Vertical Stretch by a factor of

3. c) Vertical Shift down by 2 units.

d) Horizontal Shift right by 4 units.
