To determine whether the function represented by the table is linear or nonlinear, we can analyze the values of \( y \) for the corresponding \( x \) values.
Given values: \[ \begin{align*} x & : 0, 1, 2, 3, 4 \ y & : 0, 1, -5, 8, -8 \end{align*} \]
Step 1: Graph the points
Let's plot the points:
- \( (0, 0) \)
- \( (1, 1) \)
- \( (2, -5) \)
- \( (3, 8) \)
- \( (4, -8) \)
Step 2: Check for a consistent slope
For a function to be linear, the difference in \( y \) values divided by the difference in \( x \) values (the slope) must be constant.
-
From \( (0, 0) \) to \( (1, 1) \):
- Slope = \( \frac{1 - 0}{1 - 0} = \frac{1}{1} = 1 \)
-
From \( (1, 1) \) to \( (2, -5) \):
- Slope = \( \frac{-5 - 1}{2 - 1} = \frac{-6}{1} = -6 \)
-
From \( (2, -5) \) to \( (3, 8) \):
- Slope = \( \frac{8 - (-5)}{3 - 2} = \frac{13}{1} = 13 \)
-
From \( (3, 8) \) to \( (4, -8) \):
- Slope = \( \frac{-8 - 8}{4 - 3} = \frac{-16}{1} = -16 \)
Step 3: Conclusion
Since the slopes between different points are not constant (1, -6, 13, -16), the function does not represent a straight line and is therefore nonlinear.
Answer:
The function is nonlinear.
