What is the domain and range of the step function with the equation below? f(x) = -3[ x ]
2 answers:
Answer:
Option C.
Step-by-step explanation:
The given function is
We need to find the domain and range of the given step function.
is least integer function. The output of this function is all integers and it is defined for all values of x.
The given function is 3 times of least integer function. So, the given function f(x) is defined for all real number and outputs of the function are all integers that are multiples of 3.
Domain of f(x) = All real numbers = (-∞,∞)
Range of f(x) = All integers that are multiples of 3.
Therefore, the correct option is C.

ANSWER: The size of a red blood cell IS approximately half the size of a plant cell.
EXPLANATION:
<em>1. We divide the size of the plant cell by 2 to see if half of its size is the size of a red blood cell. </em>
Therefore, half of a plant cell's size is 0.000006325 m.
<em>2. We now compare the size of half of the plant cell to the size of the red blood cell.</em>
0.000006325 m and 0.000007 m are very close in size; therefore, the size of a red blood cell IS approximately half of a plant cell.
