26 Let Sd give the height of high tide in Seattle on a spe c

26. Let S(d) give the height of high tide in Seattle on a spe- cific day, d, function S(d) to of the year, Use shifts of the find formulas for each of the following functions: (a) T(d), the height of high tide in Tacoma on day d, if we assume that high tide in Tacoma is always one foot higher than high tide in Seattle. (b) A(d), the height of high tide in Astoria on day d, if we assume that high tide in Astoria is the same height as the previous day\'s high tide in Seattle.

Solution

26) S(d) is the formula for seattle high tide

a) T(d) formula when tacoma is one foot higher than high tide in seattle

T(d) = S(d) + 1

b) Astoria high tide is same as previous days hight tide in seattle

which means Astoria high tide is

A(d) = S( d-1 )
