The solutions to the equation are the x-coordinates of the points where the graphs of these functions intersect. Think of it as a treasure hunt where the intersection points mark the location of the hidden treasure (the solution!).

  • Example: To solve the equation x2 = 2x + 3, graph the functions y = x2 and y = 2x + 3. The x-coordinates of the intersection points will be the solutions to the equation.
  • Benefits: This method is particularly useful for equations that are difficult or impossible to solve algebraically.

Solving Inequalities Graphically: Shading the Solution Region

Solving inequalities graphically is similar to solving equations, but with an added twist: we're looking for regions rather than specific points. First, graph the functions on either side of the inequality. Then, identify the region(s) where one graph is above (or below, depending on the inequality) the other graph. Shading these regions visually represents the solution set.

  • Example: To solve the inequality x2 > 2x + 3, graph y = x2 and y = 2x + 3. The solution is the set of x-values where the parabola (y = x2) is above the line (y = 2x + 3).

Knowing the key features of a graph is crucial for analysis. This includes things like:

  • Intercepts: Where the graph crosses the x and y axes.
  • Turning Points: Maximum and minimum points on the graph.
  • Asymptotes: Lines that the graph approaches but never touches.
  • Symmetry: Whether the graph is symmetrical about the y-axis (even function) or the origin (odd function).

Transformations: Shifting, Stretching, and Reflecting

Understanding how to manipulate graphs through transformations is super important. Think of it like this: you have a basic graph, and you're using transformations to mold it into the shape you need to model a specific situation. Singapore JC2 H2 Math Tuition often emphasizes this concept because it forms the basis for many problem-solving techniques.

Interesting Fact: Transformations can be represented by matrices! This is a powerful tool in linear algebra and can simplify complex transformations.

Modelling Real-World Situations with Graphs

This is where the magic happens! Real-world modelling involves translating a problem described in words into a mathematical equation and then representing that equation graphically. Let’s look at how to do this effectively.

Formulating Equations from Data

Often, you'll be given a set of data points and asked to find an equation that fits the data. This might involve:

  • Identifying the type of function: Does the data look linear, quadratic, exponential, or something else?
  • Using regression techniques: If you have a lot of data, you can use a calculator or computer software to find the best-fit equation.
  • Solving for constants: Once you know the type of function, you need to find the values of the constants that make the equation fit the data.

Analysing Trends and Making Predictions

Once you have a graph, you can use it to analyse trends and make predictions. For example:

  • Finding the maximum or minimum value: This could represent the maximum profit, minimum cost, or optimal time.
  • Determining the rate of change: This tells you how quickly something is changing.
  • Extrapolating beyond the data: This involves using the graph to predict what will happen in the future. Be careful with this, though! Extrapolation can be unreliable if you go too far beyond the data.

History Snippet: The use of graphs to model real-world phenomena dates back centuries. Early astronomers used graphs to track the movements of planets, and economists used them to study market trends.

Example: Modelling Population Growth

Let's say you're given data on the population of a town over several years. You might notice that the population is growing exponentially. You could then use this data to create an exponential function that models the population growth. This model could then be used to predict the population in future years. This is a common type of question in Singapore H2 Math exams.
