Well the variance is how close or far the points are from the mean.. so if it is a large variance then the sample with be very spread out. If your variance is large then your standard deviation is also large.
Okay so here we have the function f(x)=3x-6 if you plug in -2 to x you get -12 if you plug in -1 you get -9 and if you plug in 0 you get -6 add three each time
