+37155 Just find TWO x inputs that are 3 units apart....like -5 and -2 and calculate the difference of f(x) between those two
x = -5 f(x) = -11
x = -2 f(x) = ? (what do you see on your table?) then calculate the difference....usually the absolute value of the difference....
I think you can do that......can ya?
