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 :)

step-by-step explanation:

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
