Question

What is the relative maximum value for the function:
7/x^2+5?

harsimran_hs4 · Answer

can you rewrite the expression(using equation generator or proper brackets) ?

ybarrap · Answer

Is this the problem? $$7/x^2+5 $$

anonymous · Answer

7/(x^2+5)

harsimran_hs4 · Answer

so 7 is constant you just need to maximize (1/(x^2+5))
or minimize (x^2 + 5)
so what is the minimum value of (x^2 + 5) ?

anonymous · Answer

That's what I don't understand how to do

harsimran_hs4 · Answer

consider our problem 
minimize (x^2 + 5)
since 5 is a constant so we just need to minimize x^2, 

x^2 is always greater than or equal to 0. so the x^2 `s minimum value is 0

x^2 + 5 `s is 5
so 7/5 should be the final answer
 clear ?

Somewhat. What exactly does it mean when it asks for the relative maximum instead of absolute maximum?

harsimran_hs4 · Answer

Relative maximum is a maxima which is determined locally (say about a point)|dw:1374342841668:dw|
