Which function has the greater rate of change?
a. function 1
b. function 2

The function with the greatest change is B.) Function 2

Using the  trick to find the slope, we can tell which function has the greatest change.

The slope of Function 1 = 

The slope of Function 2 = 

So, since Function 2 has the greatest slope, or highest incline in its linear function, it has the greatest rate of change.

I hope this helped!! Have a blessed day :D
