Question: Suppose r(x) and t(x) are two functions with the same domain, and let h(x)=r(x)+t(x). Suppose also that each of the 3 functions r, t and
Supposer(x)andt(x)are two functions with the same domain, and leth(x)=r(x)+t(x).
Suppose also that each of the 3 functionsr, tandh, has a maximum value in this domain (i.e. a value that is greater than or equal to all the other values of the function).
- LetM= the maximum value ofr(x),
- N= the maximum value oft(x),and
- P= the maximum value ofh(x).
How might the following always be true thatM+N=P?
