For this case we have the following function:
 h (x) = - 5x ^ 2 + 10x + 15

 By the time the stone is thrown, x = 0.
 We must evaluate this value of x in the function.
 We have then:
 h (0) = - 5 (0) ^ 2 + 10 (0) +15

h (0) = 0 + 0 + 15

h (0) = 15 meters
 Answer:
 The height of the stone at the time is thrown is given by:
 h (0) = 15 meters
