Interpreting graphs of functions is an important skill in Year 10 Mathematics. It helps you connect math to real-life situations. Let’s break it down in a simpler way!
Graphs are pictures that show mathematical relationships.
Each point on the graph matches a specific value of the function.
For example, if we look at a simple line like (y = 2x + 3), we can plot points like these:
When (x = 0):
(y = 2(0) + 3 = 3) (this gives us the point (0, 3))
When (x = 1):
(y = 2(1) + 3 = 5) (this gives us the point (1, 5))
Once you have your points on the graph, you draw a line through them.
This line helps you see how changes in (x) affect (y).
Graphs are also used to show real-life situations, like tracking your expenses over time.
Imagine you have a graph showing how much a mobile phone plan costs each month.
Each point on the graph shows the total cost up to that month.
By looking at how steep the line is, you can see how fast your expenses are going up.
Think about a graph showing how far a car travels over time.
If the line is steep, the car is going fast.
If the line is flat, that means the car isn't moving.
By reading these lines and points, you can figure out when the car needs gas or when to slow down!
Using graphs in your math learning helps you understand how math relates to everyday life.
So, next time you see a graph, ask yourself what it really means in that situation!
