Six common questions when applying Conditional Formatting:
Use of Colour Scale:
Colour Scales apply a gradient of colors to cells based on their value in relation to other cells in the range.
- Highest values are assigned one color (e.g., green),
- Lowest values another color (e.g., red),
- Middle values get a blend (e.g., yellow).
This provides a visual heatmap-like representation to help users instantly interpret large sets of numerical data.
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.
