So this is going to be equal to two plus 1.4 times 0.36 is 0.9, or 0.09. So this is going to be equal to, this is going to be equal to 2.09. So that is our approximation, and it should be, at least based on how I graphed it, a little bit higher than the actual value of the square root of 4.36. But we could write that up here. This is going to be approximately, let me just write it this way. The square root, I'll just write it down here. So we could say the square root of 4.36, which is the same thing as f of 4.36, this is approximately equal to 2.09.
