Answer:
A florist has 25 flower arrangements to sell. Practical domain of f(x) = { x : x > 0 and x <= 25}.
Solution:
Number of arrangements of flower to sell = 25
Amount of money generated by selling flower = 15x where x represents flower arrangements.
So x can have possible values of 1 to 25
“x” cannot be zero or negative as it make no sense of counting flower arrangements as 0 or negative.
So practical value of x that is practical domain of f(x) = 15x is x = { 1 , 2 , 3 ,4 ……. 25 }
Or domain of f(x) = { x : x > 0 and x <= 25}
