When taking square roots, you can't take square roots of negative roots of negative numbers. So, what will work for the domain of u(x) is what makes u(x) zero or more. We can make an inequality for that.
u(x) ≥ 0.

9x + 27 ≥ 0 by squaring both sides
9x ≥ -27
x ≥ -3
So the domain of the function is when x ≥ -3 is true.
Consider a function f(x), the linear approximation L(x) of f(x) is given by

Given the quantity:

We approximate the quantity using the function

, where x = 203.
We choose a = 200, thus the linear approximation is given as follows:
Answer:
I would say -19, not 100% sure tho!
