-f(x) of f(x)=4x^2+5x+4
@thomasker
if we have f(x) = 4x^2+5x+4 and there is a -f(x) then we have -(4x^2+5x+4). All you have to do is distribute the negative.
Here you just got to put a minus in front of the function, so all the plusses become minus and vice versa: \[-f(x) = -4x^2-5x-4\]
welp what @thomasker and @UsukiDoll said would be dead on
you know it would be helpful if I see attempts at least on these problems. I deal with way harder stuff than this...
@thomasker no it is just replace x by -x all the places in the given equation
and what about f(h+x)??
replace all x's with the h+x if you have f(h+x)
then replace x by ''h+x''
this going downhill fast
@Haseeb96 if it was replacing x by -x the question wasn't -f(x) but is would be f(-x)
you have to do at least attempt and learn the concepts behind all of this. What if you have an exam and you have close notes close calculator and close textbook?
Yea, I aggree with @thomasker in this situation you would apply the negative to the entire function.
