Answer:

(1,3) and (2,4).

Explanation:

The inequality is
y > -x^2+5 , so

for (0,5):

5> -(0)^2+5

5> 0+5

5>5 , that is false, then (0,5) is not in the solution set of
y > -x^2+5 .

for (1,3):

3> -(1)^2+5

3> -1+5

3>4 , that is false, then (1,3) is not in the solution set of
y > -x^2+5 .

for (2,4):

4> -(2)^2+5

4> -4+5

4>1 , that is true, then (2,4) is in the solution set of
y > -x^2+5 .
