Question 1
Find the inverse of the following function: f(x) = (x - 3)
2, if x ≥ 3.
◦ f
-1(x) = 2 +

◦ f
-1(x) = 3 +

◦ f
-1(x) = 3 -

◦ f
-1(x) =

◦ f
-1(x) = 1 +

Question 2
Find the inverse of the function f(x) = x
2 - 8x + 4, where x ≤ 4. State its domain.
◦ f
-1(x) = 4 +

. Domain is x ≥ 12.
◦ f
-1(x) = 4 -

. Domain is x ≥ -12.
◦ f
-1(x) = 4 -

. Domain is x ≥ 12.
◦ f
-1(x) = 4 +

. Domain is x ≥ -12.
◦ f(x) has no inverse.
