Math Problem Statement
Solution
Let's analyze the table of values in the image.
We are given the following inputs and outputs for a linear function:
Input | Output |
---|---|
1 | -4 |
2 | 0 |
3 | 4 |
4 | 8 |
n | ? |
To find the pattern, notice the output changes with a constant difference as the input increases by 1. Specifically:
- From input 1 to input 2:
- From input 2 to input 3:
- From input 3 to input 4:
The output increases by 4 for every increase of 1 in the input, confirming this is a linear function with a constant rate of change.
Step 1: Determine the slope
The slope (rate of change) is 4, which means the linear function has the form:
Step 2: Find the y-intercept
Using the point (1, -4):
Thus, the equation of the linear function is:
Step 3: Calculate the output for input
The output when the input is is:
Thus, the output for the input is .
Would you like more details or clarifications? Here are some related questions to consider:
- How can you use two points to find the equation of a line?
- Why is the slope the same between any two consecutive points on a linear function?
- How do we determine the y-intercept from a table of values?
- Can this method be used for other types of functions (e.g., quadratic, exponential)?
- How do you apply this function to predict other outputs beyond those in the table?
Tip: Always check for a constant rate of change when analyzing tables of linear functions. It ensures the function is indeed linear.
