Answer:
Her height above the water at the time of diving is 15 meters.
Step-by-step explanation:
Given function that shows the height of Ana above the water ( in meters ) after diving,
[tex]h(x)=-5(x+1)(x-3)[/tex]
Where, x is the number of seconds after diving,
Since, at the time of diving x = 0,
Hence, the height of her at the time of diving,
[tex]h(0)=-5(0+1)(0-3)[/tex]
[tex]=-5(1)(-3)[/tex]
[tex]=15\text{ meters}[/tex]
