The retail flat rate in dollars for first-class mail weighing up to 5 ounces could be computed by the piecewise-constant function f, where x is the number of ounces.(a) Evaluate f(3.8) and f(5). (b) What is the domain of f? What is the range of f?

The Retail Flat Rate In Dollars For Firstclass Mail Weighing Up To 5 Ounces Could Be Computed By The Piecewiseconstant Function F Where X Is The Number Of Ounce class=

Answer :

a)

f(3.8)=1.36

f(5)=1.58

where f(x) represents the retail flat rate in dollars and x is the number of ounces

b)

The domain of the function is the set of all possible values of x in this case

[tex](0,5\rbrack[/tex]

The range of the function is the set of all possible values the function can have

[tex]\lbrace0.70,0.92,1.14,1.36,1.58\}[/tex]
