The function Q is a linear function because the function Q has a constant rate
The functions are given as:
A linear function is represented as:
y = mx + b
Where m represents the slope, and b represents the y-intercept
By comparing y = mx + b to the functions, we can see that the function Q is a linear function.
This is so because the function Q has a constant rate, while the function P does not have a constant rate
