Answer:
Function A
Explanation:
Function A: y = 12x + 3
The coefficient of x is 12. This means that for every increase of 1 unit in x, y will increase by 12 units. So, the rate of change for Function A is 12.
Function B: y = 2x − 4
The coefficient of x is 2. This means that for every increase of 1 unit in x, y will increase by 2 units. So, the rate of change for Function B is 2.
We see that
12 > 2
So, function A has a greater rate of change.
