The function shown models the depth d (in inches) of snow on the ground during the first 9 hours of a snowstorm, where t is the time in hours after the snowstorm begins.

answer: 4

step-by-step explanation:

the expected value of the random variable : 0, 1 and 2

step-by-step explanation:

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )

x-3y=4
