Answer: 15 meters

Step-by-step explanation:

Given the relation:

h (x) = - 5 (x+1) (x-3)

Where h is the height at time 'x' after diving

At the time of diving, time 'x' = 0, that her height just before making the dive

Therefore,

h (0) = - 5 (0 + 1) (0 - 3)

h = - 5 (1) (-3)

h = - 5 * - 3

h = 15

Therefore, h = 15 meters
