Step-by-step explanation:
(a○b)(x) is the same as a(b(x)).
it is really that simple.
first you calculate the result of the inner function, and then that result is the input for the outer function.
that's it.
so,
(w○u)(2) = w(u(2))
u(2) = -2 -1 = -3
w(-3) = 2×(-3)² + 1 = 2×9 + 1 = 19
so, 19 is the first answer.
(u○w)(2) = u(w(2))
w(2) = 2×2² + 1 = 2×4 + 1 = 9
u(9) = -9 - 1 = -10
so, -10 is the second answer.

Answer:
Step-by-step explanation:
Researcher observes that 12 out 15 cats that approached him are males.
Therefore, number of Female Cats that approached him = 15 – 12 = 3
From the four graphs presented, it is expected the only one with a negative correlation coefficient is the third graph or graph c.
<h3>What is a negative correlation?</h3>
This occurs when the two variables analyzed go in opposite direction, which means one increases and the other decreases.
<h3>How is this represented in a graph?</h3>
In a graph, a negative correlation coefficient is related to a negative slope.
This negative slope can be seen in the third graph or graph C.
