Answer:
The rate of change of the function is 9
Step-by-step explanation:
Mathematically, the rate of change of the function refers to the slope of the line that passes through the given points
Thus, we use the slope equation as follows;
m = (y2-y1)/(x2-x1)
(x1,y1) = (6,6)
(x2,y2) = (7,15)
Substituting these values, we have
m = (15-6)/(7-6) = 9/1 = 9
