Edges are narrow, linear planting areas that define boundaries between different zones such as lawn and flower beds, pathways, or garden sections. They create structure, guide movement, and enhance aesthetics by providing clean, organized lines within landscape design.
Plants selected for edging should be compact, dense, and easy to maintain. Common examples include:
Draw a rough sketch for the curve $y = 2 + |x + 1|$. Using integration, find the area of the region bounded by the curve $y = 2 + |x + 1|$, $x = -4$, $x = 3$, and $y = 0$.
In a Linear Programming Problem (LPP), the objective function $Z = 2x + 5y$ is to be maximized under the following constraints:
\[ x + y \leq 4, \quad 3x + 3y \geq 18, \quad x, y \geq 0. \] Study the graph and select the correct option.
