Suppose h(t) = -5° +10t + 3 represents the height of a diver above the water, in meters, t seconds after the diver leaves the springboard. Approximately when does the diver hit the water?

A. after 1 second
B. after 2 seconds
C. after 3 seconds
D. after 8 seconds​

answer: 1 2 3 6

step-by-step explanation:

1x6=6 2x3=6

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option
