Hello MHB,
I am solving some old exam and I am stuck at one problem
it says 'outline the following two amounts'
If we start with number 1.
we know for the part \(\displaystyle (x-1)(x-5)\leq0\) x has to be \(\displaystyle 1\leq x \leq 5\)
part number 2.
\(\displaystyle (x-3)(x-4)>0\) we know that \(\displaystyle x>4\)
part number 3.
\(\displaystyle (x-2)(x-6)\leq0\) we have\(\displaystyle 2\leq x\leq6\)
for number 1 and 2 we got
\(\displaystyle 4 < x \leq 5\)
and part 2 and 3 we got:
\(\displaystyle 4<x \leq 6\)
Is this correct?
Regards,
\(\displaystyle |\rangle\)
