How do you find the average rate of change of #f(x)= (3x^2-x)/2# from (8,10)?
1 Answer
Average rate of change
Explanation:
Use the slope formula to find average rate of change:
#m=(y_2-y_1)/(x_2-x_1)#
To use the slope formula, you need 2 points on the curve - we only have to x values, so we need to find f(8) and f(10).
#f(8)=92#
#f(10)=145#
These means are points are
#m = (145-92)/(10-8)#
#m=53/2#
#m=26.5#
