Modelling with Functions (Edexcel A-Level Mathematics): Flashcards

Understand the problem and identify the variables.

$y = kx$, where $k$ is a constant.

Quadratic functions: $y = ax^2 + bx + c$.

For growth and decay scenarios.

To solve exponential equations and model growth/decay.

Profit = Revenue - Cost, where values are defined.

Profit $P(x) = 0$, indicating no loss or gain.

Solve $3x - 1000 = 0$ for $x$.

Interpret results in the context of the original problem.
