Answer 2

To find the value of f(16), we need to apply the function f(x) to the input value x = 16. The function f(x) is defined as follows:

1. For x < 0, f(x) = -x^2
2. For x ≥ 0, f(x) = √x

Since x = 16 is greater than or equal to 0, we will use the second part of the function to calculate f(16):

f(16) = √16

Now, √16 = 4 because the square root of 16 is 4.

Therefore, f(16) = 4.
