  • Increasing Functions: , , ,
  • Decreasing Functions: , , , ,

Solution

To determine whether each function is increasing or decreasing, we can analyze the slope of each linear function. The slope of a linear function in the form is given by the coefficient :
  • If , the function is increasing.
  • If , the function is decreasing.
  • If , the function is constant.
Now, let’s analyze each function:
  1. : The slope (increasing).
  2. : The slope (increasing).
  3. : The slope (decreasing).
  4. : The slope (decreasing).
  5. : The slope (decreasing).
  6. : The slope (increasing).
  7. : The slope (decreasing).
  8. : The slope (decreasing).
  9. : The slope (increasing).

Summary:

  • Increasing Functions: , , ,
  • Decreasing Functions: , , , ,

Alright, let’s dive into the world of functions and their behavior!
For the function , since the coefficient of is positive (4), this function is increasing everywhere. It’s like a party invitation; the more you bring, the more fun you have!
Conversely, for , the negative coefficient (-2) means this function is decreasing. Think of it like a balloon losing air; as increases, the value of deflates.
Now let’s take a look at the others! Functions like (increasing), (decreasing), (decreasing), (increasing), (decreasing), (decreasing), and (increasing) follow the same pattern based on their slopes. An easy rule to remember: If the slope (coefficient of ) is positive, your function is rising like a sun; if it’s negative, it’s setting like the evening sun!
