Find the following <br> (u•w)(2)=<br> (w•u)(2)=

Viefleur [7K]

Answer:

$(u \circ w)(2) = -34$

$(w \circ u) = -49$

Step-by-step explanation:

We are given these following functions:

$u(x) = 4x + 2$

$w(x) = -5x + 1$

The first step to solve this question is finding the composite functions. So

$(u \circ w)(x) = u(w(x)) = u(-5x+1) = 4(-5x + 1) + 2 = -20x + 6$

$(w \circ u)(x) = w(u(x)) = w(4x + 2) = -5(4x+2) + 1 = -20x - 9$

At x = 2

Now we replace x by 2 in each of the functions. So

$(u \circ w)(2) = -20(2) + 6 = -40 + 6 = -34$

$(w \circ u)(2) = -20(2) - 9 = -40 - 9 = -49$
