Aflorist has 25 flower arrangements to sell. the amount of money the florist makes for selling x flower arrangements is represented by a function.

f(x)=15x

what is the practical domain of the function?

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}

step-by-step explanation:
