How tall is a building if a stone dropped from its top in free-fall strikes the ground with a velocity of 40 m/s? assume that the original velocity is zero.
a. 78.2 m
b. 80.4 m
c. 79.8 m
d. 81.6 m

9 x 8 divided by (5-3)=36

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
