What is the domain of the step function f(x) = ⌈2x⌉ – 1? {x| x ≥ –1} {x| x ≥ 1} {x| x is an integer} {x| x is a real number}

Domain of f(x) = ⌈2x⌉ – 1 is {x| x is a real number}.

Step-by-step explanation:

Given : f(x) = ⌈2x⌉ – 1.

To find : What is the domain of the step function .

Solution : We have given that  f(x) = ⌈2x⌉ – 1.

Domain : domain is the set of  input values for which function is defined or real.

f(x) = ⌈2x⌉ – 1 is a linear function and it is defined for all real values.

Therefore , Domain of f(x) = ⌈2x⌉ – 1 is {x| x is a real number}.

Answer is D; {x| x is a real number}

Got a 100% on the quiz :)

a.) list the factors of 40.

1/2/4/5/8/10/20/40

b.) list the factors of 40 that represent the number of cans that could be on each shelf.

5

c.) how many different arrangements of cans are possible?

just one because if you put more on one shelf you will go way over 40 and the cabinet will probably break.

d.) what are the possible arrangements of the cans?

put 5 cans on each self to reach 40 cans in total.

e.) which arrangement uses all the shelves?

5 because you can put 5 cans on each shelf, and since there are 8 shelfs you are equally going to get 40 cans.
