Question

Number of integers in range of $x$ which satisfies the following

$\frac{x-2}{x+4}\le 0$

Answer 1

The values of x that satisfy this equation must lie between $-4$ and $2$.

The integral values are $\{-3,-2,-1,0,1,2\}.$

$-4$ can not be included as it will render the expression undefined. Correct answer is $6$.
