Answer 1

Hi there your answer

| cos (x) -2 | lies between [1, 3]

Therefore, $1≤a2−2a+3≤3$

Now Solving LHS, we get $\Rightarrow a^2 - 2a +2 \geq 0 \Rightarrow (a-1)^2 +1 \geq 0$

This is true for all  "a belongs to all real number".

Solving RHS, we get a2−2a≤0abelongsto$[0,2]$

There fore intersection of both leads to a belonging to [0, 2] with three integer values.
