<h2>(0,1) and (2,5).</h2>Step-by-step explanation:
The graph of the inequality is attached.
Remember, a solution of an inequality is a point on the shaded region. Also, it must satisfy the inequality expression
From the graph we know the possible answers are (0, 1) and (2, 5), let's prove it.
<h3>For (0, 1):</h3>Which is true, so (0, 1) is solution.
<h3>For (2, 5):</h3>Which is true, so (2, 5) is solution.
Therefore, the solutions are (0,1) and (2,5).
