ANSWER
4. y = –2 x – 1
5. y = x + 3
6. y = x – 2 + 53
domain: x > 0, range: y < 1
domain: x > 3, range: y > 0
domain: all real numbers,range: all real numbers
Prerequisite Skills SKILL CHECK
Find the inverse of the function.
7. y = 3x + 5
8. y = –2x3 + 1
9. y = x2, x ≥ 012
ANSWER y = 2x
– 2x – 1ANSWER 3y =
x – 5ANSWER y = 3
