NEED ASAP! A fountain sprays water into a pool as part of the filtration system. The projected path of water is modeled by the function given in the table, where x represents the time in seconds since the water left the fountain and f(x) represents the height in feet above the pool’s water line. How many seconds does the water travel through the air? A. –6 B. 1.5 C. 3 D. 5

The correct answer is C. the water goes through the air for only 3 seconds.

D is inncorrect because if the height of the water is negative, then it is no longer in the air.

Step-by-step explanation:

4th option is correct xy=-10

if this was to u plzz mark me the brainliest

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
