function help given f(x) = 4√-x find:
1. f(4-x)
2. f(4-x^2)
3. f(4-x^4)
4. f(4x- x^2)
5. f(-x^4 - 4x^2)
pls help me for my H.w

Answer 1

replace x by the inputs and make sure to use parentheses

Answer 2

\[f(x)=\sqrt[4]{-x}\]

Answer 3

thats the given sir

Answer 4

\[f(4-x)=\sqrt[4]{-(4-x)}=\sqrt[4]{(x-4)}\]

Answer 5

thats for no.1 sir? ic i just
connect or simplify..

Answer 6

\[f(4-x^2)=\sqrt[4]{-(4-x^2)}=\sqrt[4]{x^2-4}\]\]

Answer 7

there is nothing to "simplify" here. just write what you get

Answer 8

great yes!

Answer 9

3 more to go yehey!

Answer 10

so next one is
\[f(4-x^4)=\sqrt[4]{x^4-4}\]

Answer 11

then
\[f(4x-x^2)=\sqrt[4]{x^2-4x}\]

Answer 12

and finally
\[f(-x^4-4x^2)=\sqrt[4]{x^4+4x^2}\]

Answer 13

god bless u sir thank thank you!
