Question

The functions u and w are defined as follows.
u(x)=-x-2
w(x)=-2x^(exponent 2)+1
Find the value of u(w(4))

Answer 1

No clue :/

Answer 2

Okay Not here to answer your Q just here to say

Answer 3

Yes i think i know how to solve a function

Answer 4

You cant really tell me what to do... All you had to do ws let me finnish you not my gaurdain

Answer 5

\(\large\color{red}{ \displaystyle u(x)=-x-2 }\)
\(\large\color{blue}{ \displaystyle w(x)=-2x^2+1 }\)

Find the value of u(w(4))

first, can you find \(\large\color{black}{ \displaystyle \color{red}{u}(~\color{blue}{w(x)}~) }\) ?

Answer 6

(plug in what w(x) is equal to, into u(x) instead of x.)

Answer 7

\(\large\color{black}{ \displaystyle \color{red}{u}(~\color{blue}{w(x)}~) = \color{red}{-\color{blue}{(-2x^2+1)}-2}}\)

Answer 8

then as you simplify the \(\large\color{black}{ \displaystyle \color{red}{u}(~\color{blue}{w(x)}~) }\) and plug in 4. \(\large\color{black}{ \displaystyle (}\)or ever, right away plug in and then simplify\(\large\color{black}{ \displaystyle )}\).

this will give you \(\large\color{black}{ \displaystyle \color{red}{u}(~\color{blue}{w(4)}~)}\)
