Answer:
A. -1.8
Step-by-step explanation:
If x is the independent variable and y is the dependent variable, therefore constant of proportionality would be:
k = y/x
Using any pair of values from the table, we can find k. Let's use (3, -5.4):
k = y/x = -5.4/3
k = -1.8
The definition of the piece-wise function is:

<h3>What is a piece-wise function?</h3>
A piece-wise function is a function that has different definitions, depending on the input.
In this problem, for inputs between -2 and 2, the function is a line that goes through (-2,-4) and (2,6). The slope is:
m = (6 - (-4))/(2 - (-2)) = 2.5.
The y-intercept is of b = 1, hence the rule is:
![f(x) = 2.5x + 1, -2 \leq x \leq 2](https://tex.z-dn.net/?f=f%28x%29%20%3D%202.5x%20%2B%201%2C%20-2%20%5Cleq%20x%20%5Cleq%202)
For x greater than 2 and less than 6, the function is constant at -3, hence the rule is:
