If is the inverse of for , then for we have
More precisely,
but since the inverse is at least 8, the quantity inside the absolute is non-negative, so
Answer:
60
Step-by-step explanation: 12L + 1/2 = 72.5
72.5 - 24 - 8.5 + 20

40 + 20 = 60
(0, −2) and (2, 0)
Step-by-step explanation:
Solutions are the points of intersection
