find the domain and range of the function defined by f(x) √x-y
Answers
Answer:
First identify the input values. The input value is the first coordinate in an ordered pair. There are no restrictions, as the ordered pairs are simply listed. The domain is the set of the first coordinates of the ordered pairs.
\displaystyle \left\{2,3,4,5,6\right\}{2,3,4,5,6}
Answer:
Step-by-step explanation:
value of x value of [x] f(x)=−∣x∣ whether real number
2 |2 |=2 -2 yes
1 |1|=0 -1 yes
0 |0|=0 0 yes
-1 |-1|=1 -1 yes
-2 |-2|=2 -2 yes
Here we are given a real function
Hence, both domain and range should be real numbers
From the above table
X can be any real number
and f(X) will always be negative or zero
All these are real values.
Here, value of domain $(Xx$$ can be negative number
Hence, Domain =R (all real number)
we note that the range f(x) is 0 or negative numbers
So, range cannot be positive
Hence, Range =Non positive real number.
