Find the average rate of change for f(x) = x2 − 3x − 10 from x = −5 to x = 10.

Average rate of change = 2

Step-by-step explanation:

Find the average rate of change for f(x) = x^2 − 3x − 10 from x = −5 to x = 10.

f(-5) = (-5)^2 − 3(-5) − 10 = 25 + 15 - 10 = 30

f(10) = 10^2 − 3(10) − 10 = 100 - 30 - 10 = 60

Average rate of change:

   f(10) - f(-5)                     60  -  30                         30

=   =    = 2

     10 - (-5)                            15                               15

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
