So one plus 2.5 is going to be 3.5. And then finally f of seven, f of seven is going to be one plus 0.1 times seven squared. So this is 49 times 0.1. 49 times 0.1 is 4.9 plus one, so plus 5.9. And so what is this going to be equal to? So let's see, 1.1 plus 1.9, these two are going to sum up to be equal to three. And then these two are going to sum up to be, let's see, if we add the five, we get to 8.5, and then we add the 0.9, we get to 9.4.
