+21 This Is the last thing i need help with today, Anything is greatly appreciated as my mind is blank ATM. 
+128407 Average Rate of change =
[ f(8) - f(0) ] / [ 8 - 0 ]
f(8) = [ 2(8) - 1] / [ 3(8) + 5] = 15/ 29
f(0) = [ 2(0) - 1] / [ 3(0) + 5 ] = - 1/5
So....average rate of change is
[ 15/29 - -1/5 ] / 8 =
[ 15/29 + 1/5 ] / 8
[ ( 75 + 29) / 145 ] / 8 =
[ 104] / [ 145 * 8 ] =
13 / 145
