Domain of a binary relation: R = [(x, y) { y = -2x + 1} is the set of {0,4,8}. Find its range?
- [-1, -9, -17]
- [0, 7, -16]
- [1, 9, 15]
- None of these
Explanation
To find the range of the binary relation R, substitute each value of x from the domain {0, 4, 8} into the equation y = -2x + 1:
For x = 0:
y = -2(0) + 1
= 1
For x = 4:
y = -2(4) + 1
= -7
For x = 8:
y = -2(8) + 1
= -15
The corresponding y-values are {1, -7, -15}. Adding 2 to each element in the set {-1, -9, -17} gives the range.
