5.) write the series in Sigma notation
8t 11 +14+17+20+23+26+2a

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

their is no graph showing

step-by-step explanation:

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

the first option is the answer.
