Question

how do you solve (f(1+4)/f(1+4))-(1/4)(4/f(1))? please explain...

Answer 1

do we know the function f(x)?

Answer 2

nope

Answer 3

there was a graph though....

Answer 4

ok then, without the graph all we can do is say
(f(1+4)/f(1+4))-(1/4)(4/f(1))=1-1/f(1)
because
f(1+4)/f(1+4)=1
and (1/4)(4/f(1)=1/f(1)
so
1-1/f(1)
is as simplified as we can make this

Answer 5

ok thanks! and also, how would you do:
