Complete the table.

y = f(g(x)) u = g(x) y = f(u)
y = (x + 18)^(-1/2) u = ? y=?

Use the chain rule.

Not sure why the bother with saying u=g. Might as well just stay with u. Anyway,

u = x+18
y = f(u) = 1/√u = 1/√(x+18)

To complete the table, we need to find the values of u and y based on the given equation y = f(g(x)).

Let's start by finding the value of u using the equation u = g(x).

Given that u = g(x), we need to substitute the value of x in the equation to find u. However, since the equation for g(x) is not provided, we cannot directly find the value of u.

To find the value of u, we need additional information about the function g(x).

Once we have the value of u, we can substitute it in the equation y = f(u) to find the value of y.

Therefore, without the equation for g(x) or any additional information, it is not possible to complete the table.
