The box and whisker plots below show two classes' semester grades. Be sure to compare the extremes, quartiles, medians, and the different types of ranges.

The first box had a greater median, the second box has a greater range than the first box. I wish i could give you more but thats all I got.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
