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

anonymous · Answer

replace x by the inputs and make sure to use parentheses

anonymous · Answer

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

anonymous · Answer

thats the given sir

anonymous · Answer

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

anonymous · Answer

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

anonymous · Answer

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

anonymous · Answer

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

anonymous · Answer

great yes!

anonymous · Answer

3 more to go yehey!

anonymous · Answer

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

anonymous · Answer

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

anonymous · Answer

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

anonymous · Answer

god bless u sir thank thank you!
