Question

TRUE OR FALSEEEE

for every a and b in R, if a 13 years ago

Answer 1

false, that is true only for monotone functions

Answer 2

i got true, do you have a example?

Answer 3

i picked any polynomial which was continuous and it was true for all of them

Answer 4

let f(x)=x^2 then -3>-5, but f(-3)<f(-5), 9< 25, cause the statement a<b, f(a)<f(b) is true only for monotone increasing functions

Answer 5

so then isnt this true then :s why is it false

Answer 6

O SORRY i should define this, f denotes a continuous function from R to R
