Thank you for the opportunity to help you with your question! the solution is as such:
The avg rate of change between two points x= 1 and x= 2 can be calculated as the slope of
line between (a, f(a)) and (b, f(b)).
So slope = (y2 - y1) /( x2- x1)
Slope = (11- 18) / (1-2)
Slope = 7
So the avg rate of change is 7.
