So this is going to be, actually we could factor out a two. So this is going to be equal to two times, f of one is one plus 0.1 times one squared. So it's one plus 0.1, so it's one point, let me color code a little bit so we can keep track of things. So this right over here is one point one. So one plus 0.1 is 1.1. This right over here, f of three, so it's one plus 0.1 times three squared, nine. So one plus 0.9.
