The rate of change of function 1 is 0 since it is a horizontal line. The rate of change of function 2 is the coefficient of x in the equation, which is 8.
So, the rate of change of function 2 is 8, which is 8 more than the rate of change of function 1.
Therefore, the correct answer is 8.
The graph represents function 1, and the equation represents function 2:
Function 1
A coordinate plane graph is shown. A horizontal line is graphed passing through the y-axis at y = 4.
Function 2
