Question

The functions u and w are defined as follows.
u(x)=−x-1
w(x)=−2x^2-1
Find the value of w(u(5))

Answer 1

first find \(u(5)\)
do you know how to do that?

Answer 2

plug in 5. so u(5) = -6

Answer 3

yes
now find \(w(-6)\)

Answer 4

w(-6)=-73

Answer 5

yes and that is your final answer

Answer 6

it is \[w(u(5))=w(-6)=-73\]

Answer 7

The functions s and t are defined as follows.
s(x)= -2x-2
t(x)= -2x^2-2
Find the value of
t(s(−5))
.

Answer 8

s(x) = 8 @satellite73
