Increasing, Decreasing or Constant? (Reading Graphs) — Easy Worksheet 2
Grade 8 · Whoobee Name: ____________________ Date: __________
Use the graph. Write increasing, decreasing or constant.
How to solve
Read the graph from left to right, between the two x-values only. If the graph goes up as x gets bigger, the function is increasing. If it goes down, it is decreasing. If it stays flat (the same y-value), it is constant.
Example
Is the function increasing, decreasing or constant from x = 0 to x = 1?
Answer: constant
Not quite. The answer is
💡 Look only between x = 0 and x = 3. There the graph goes from (0, 0) to (3, 6): it goes up from 0 to 6 as x gets bigger, so the function is increasing.
✓ Correct!
Not quite. The answer is
💡 Look only between x = 0 and x = 3. There the graph goes from (0, 0) to (3, 6): it goes up from 0 to 6 as x gets bigger, so the function is increasing.
