Answer Key
1)
Domain = All real values of x.
Range = 1 ≤ y < ∞
Type of function = It is continuous function
2)
Not a function
Domain = {1, 3 ,4, 5, 6}
Range = {1, 2, 4, 6}
3)
Domain = All real values of x.
Range = All real value of y.
Type of function = It is continuous function.
4)
Domain = 3 ≤ x < ∞
Range = 0 ≤ y < ∞
Type of function = It is continuous function.
5)
Domain = All real values of x.
Range = All real values of y.
Type of function = It is continuous function.
7)
Domain = {1, 2, 3, 4, 5, 6}
Range = {1, 2, 3, 4, 6}
Type of function = It is discrete function.
8)
Domain = All real values of x.
Range = -1/4 ≤ y ≤ 1/4
Type of function = It is continuous function.
9)
Domain = 0 ≤ x ≤ ∞
Range = All real value of y.
