The average rate of change of g(x) = 2x1 from x = 2 to x = 6 is 7.5.
true or false

g ( 2 ) = 2 * 2  1 = 4  1 = 3
g ( 6 ) = 2 * 6  1 = 12  1 = 11
11  3 = 8
6  2 = 4
8 / 4 = 2
False 
No calculations are necessary.
The function is linear, so the rate of change is constant, namely its slope which is 2
so the average rate of change is 2 , not 7.5
