Answer:
The values for the given function f is defined by
is
a)
,
b)
and
c) 
Step-by-step explanation:
Given that the function f is defined by
Now to find the value of f(0), f(18) and f(-18)
Now take f(0)
Put x=0 in the given function
we get

Therefore 
Put x=18 in the given function
we get

Therefore 
Put x=-18 in the given function
we get

Therefore 
The values for the given function f is
a)
,
b)
and
c) 
Step-by-step explanation:
first lets do the bottom rectangular prism
v = l * w * h
l = 9
w = 3
h = 3
can you work out the volume and answer in the comments
Given that the sample size is 12, thus the degree of freedom = 12 - 1 = 11.
Using technology, the p value of the t statistic, t = 2.028 is 0.9663.
