Find the inverse of the relation {(6, 11), (-2, 7), (0, 3), (-5, 3)}
{(6, 11), (-2, 7), (0, 3), (-5, 3)}
{(-6, -11), (2, -7), (0, -3), (5, -3)}
{(-11,-6),(-7, 2), (-3, 0), (-3, 5)}
{(11,6),(7, -2), (3, 0), (3, -5)}
Find the inverse of the relation {(-1, -2), (-3, -2), (-1, -4), (0, 6)}
{(1, 2), (3, 2), (1, 4), (0, -6)}
{(-2, -1), (-2, -3), (-4, -1), (6, 0)}
{(2, 1), (2, 3), (4, 1), (-6, 0)}
{(-1, -2), (-3, -2), (-1, -4), (0, 6)}
Explanation & Answer
The solutions are ready. Please ask if something is unclear.
1. 𝑦 = 𝑥 2 − 4 ≥ −4. Thus on the graph of the inverse relation 𝑥 must be ≥ −4.
So the answer is C.
2. If 𝑓(−4) = 5, then must be 𝑔(5) = −4. It is not so for the second option
(52 − 11 = 14 ≠ −4).
3. Solve for 𝑥 𝑦 =
3𝑥−5
2
: 2𝑦 = 3𝑥 − 5, 𝑥 =
2𝑦+5
3
. Thus the inver...
