Question

Identify the relative maximum value of g(x) for the function 7/x^2+5

Answer 1

oh I meant to write g(x)=7/x^2+5

Answer 2

okay, think of it this way... what can you put in for x to give you the biggest output?

Answer 3

if you put in a really big x value in, what will you get? 7/(really big number) = small number

Answer 4

so the way to get the biggest output is to put in a really small number in for x

Answer 5

So if you put in 0 then 7/0^2+5....that equals 7/5

Answer 6

exatly zero. Because when you put 0 in for x, you 7/5 which is the biggest possible number, also check out the graph at x =0
