A landscape architect is designing a garden bed that will feature a variety of native plants. The shape of the garden bed can be modeled by a polynomial function. The architect wants the design to be aesthetically pleasing and functional, considering factors such as sunlight exposure and water drainage. The garden bed’s shape is partially defined by the polynomial $P(x) = (x-a)(x-b)(x-c)^2$, where $a$, $b$, and $c$ are distinct positive real numbers representing key locations along the x-axis (in meters).
a. Explain the significance of the squared factor $(x-c)^2$ in the polynomial $P(x)$ with respect to the graph of the function and the shape of the garden bed.
