Rui is a professional deep water free diver.His altitude (in meters relative to sea level), a seconds after diving, is modeled by:d(x) = 1/2x^2 - 10xWhat is the lowest altitude Rui will reach?[ ] meters relative to sea level

Respuesta :

Lets draw a graph for our model function:

[tex]d(x)=\frac{1}{2}x^2-10x[/tex]

The graph is:

Where we can see that the lowest point is at -50 meters relative to sea level.
