Question

incorrect
your answer is incorrect.

• (w ∘ u)(3): your answer is incorrect.
• (u ∘ w)(3): your answer is incorrect.

suppose that the functions u and w are defined as follows.
u(x) = -2x - 2
w(x) = x²
find the following.
(w ∘ u)(3) = -8
(u ∘ w)(3) = 9

Explanation:

Step1: Compute $u(3)$ first

$u(3) = -2(3) - 2 = -6 - 2 = -8$

Step2: Calculate $(w \circ u)(3)=w(u(3))$

$w(-8) = (-8)^2 = 64$

Step3: Compute $w(3)$ first

$w(3) = 3^2 = 9$

Step4: Calculate $(u \circ w)(3)=u(w(3))$

$u(9) = -2(9) - 2 = -18 - 2 = -20$

Answer:

$(w \circ u)(3) = 64$
$(u \circ w)(3) = -20$
