Question

The path of a diver in the water can be modeled by the funtion y= 0.16x^2-3.2x, where x is the horizontal distance in feet that the diver travels and y is the depth in feet of the diver.
im not sure what the y-intercepts (roots) are but i already know what the vertex is (-16)

Hoot! You just asked your first question! Hang tight while I find people to answer it for you. You can thank people who give you good answers by clicking the 'Good Answer' button on the right!

Answer 2

i think x-intercept is the roots.....wats ur actual question ?

Answer 3

oh, the question is just the first sentence with the diver in it.

Answer 4

y=0.16x^2-3.2 but just dont know how to brek it dwn in numbers on my poster

Answer 5

ok,now wats ur doubt.break it down as in?sorry but, i don't get wat u want to know :/

Answer 6

no thanks i already got it on yahho .. wanna see?diff(.16*x^2-3.2*x, x) = 0.32*x - 3.2

solve(0.32*x - 3.2 = 0)

x = 10

f(x):=( 0.16 x^2 - 3.2 x)

f(10) = - 16

Vertex = (10, - 16), Minimum of f(x)

When the diver travel the first 10 feet, the depth that the diver gets is 16 feet!
