That funky circle in the middle is the composition of the function. It asks you to take a function as an input and to yield an output that's another function. It's one of the five function operations, along with adding, subtracting, multiplying, and dividing.
When you compose, you might find the notation w(u(x)) easier to understand. It's saying evaluate u then evaluate w.
For our functions, the compositions are:
u(w(x)) = u(2x²) = -(2x²) - 2 = -2x² - 2
w(u(x)) = w(-x - 2) = 2(-x - 2)² = 2(x² + 4x + 4) = =2x²+ 8x +8
Now we evaluate each composition at 4.
u(w(4)) = -2(4²) - 2 = -2(16) - 2 = -32 -2 = -34
w(u(4)) = -2(2²) +8(2) + 8 = -2(4) + 16 + 8 = -8 + 16 + 8 = 16.
Thus, u(w(4)) = -34 and w(u(4)) = 16.

d)
Answer:
Option d (convenience sample) is the right solution.
Step-by-step explanation:
- An unlikely sample wherein the investigator chooses such individuals closest and therefore most approachable for the particular investigation, would be termed as a Convenience sample.
- It's a way to gather information or data with the use of sampling advantageously positioned around a place or broadband internet.
All other alternatives aren't related to the given scenario. So the above option is correct.
