y = −5.79x + 99.14; $12.29
{(4, −12), (0, −8), (−4, −4), (−8, 0)}
Find the inverse of each relation.
Find the inverse of each function
52. {(1, 9), (13, 26), (–3, 4), (–11, –2)}
56. f (x) = 3x + 8
SOLUTION:
SOLUTION:
To find the inverse, exchange the coordinates of the
ordered pairs.
(1, 9) → (9, 1)
(13, 26) → (26, 13)
(–3, 4) → (4, –3)
Write the final equation in slope-intercept form. So,
(–11, –2) → (–2, –11)
.
The inverse is {(9, 1), (26, 13), (4, -3), (-2, -11)}.
ANSWER:
ANSWER:
{(9, 1), (26, 13), (4, −3), (−2, −11)}

SOLUTION:
54.
SOLUTION:
To find the inverse, exchange the coordinates of the
ordered pairs.
(–12, 4) → (4, –12)
Write the final equation in slope-intercept form. So, f

(x) = 4x + 28.
(–8, 0) → (0, –8)
ANSWER:
(–4, –4) → (–4, –4)
(0, –8) → (–8, 0)
60.
