Transformations have a big impact on how polynomial functions act. Let’s break it down:

1. Vertical Shifts: When you add a number, like $k$, to a polynomial $f(x)$, it moves the graph up or down. For example, if you have $f(x) + 3$, the graph goes up by 3 units.

2. Horizontal Shifts: If you change $x$ to $x - h$, it shifts the graph left or right. For instance, $f(x - 2)$ moves the graph 2 units to the right.

3. Reflections: If you multiply the function by -1, it flips the graph upside down. So, when you see $-f(x)$, it reflects the graph across the x-axis.

4. Vertical Stretch/Compression: If you multiply by a number greater than 1, like $a > 1$, it stretches the graph. On the other hand, if $a$ is between 0 and 1 (like $0 < a < 1$), it squishes the graph. For example, $2f(x)$ stretches the graph taller by a factor of 2.

Knowing about these transformations helps you understand how polynomials behave, making it easier to draw their graphs!
