Question

please someone help me,
I'll give medal and fan, pleaseeee

Answer 1

iz!!

Answer 2

hello!!

Answer 3

lets go g first because it is easy

Answer 4

the largest cosine can be is 1
so the largest 2 times cosine can be is 2
so the largest 2 times cosine +4 can be is 6

Answer 5

so I only have to answer for f or g?

Answer 6

no i think misty meant do g first
now we can do f

Answer 7

pretty much along the same lines of reasoning as \((x-3)^2\geq0\) so \(-4(x-3)^2\leq 0\) and therefor
\[-4(x-3)^2+3\leq 3\]

Answer 8

could you explain it in words? im pretty slow when it comes to this lol

Answer 9

to recap, the maximum value of \(f\) is 3
the maximum value of \(g\) is 6

Answer 10

yeah sure

Answer 11

\((x-2)^2\) is a square and a square is never negative

Answer 12

that means it is always greater than or equal to zero

Answer 13

when you put a minus sign in front, that means it is always less than or equal to zero

Answer 14

when you add 3 out at the end, that means it is always less that or equal to 3

Answer 15

wait... im so confused. so for f(x) we can say that because the negative and the minus sign, it changes its value to greater? @satellite73
