The graph of the function f(x) = –(x + 1)2 is shown.

Use the drop-down menus to complete the statements.

In order for f–1(x) to be a function, the domain of f(x) can be restricted to  

✔ x ≥ 1

.

Under this restriction, the domain of f–1(x) would be  

✔ x ≥ 2

, having the same minimum value as the  

✔ range of f

.

Step-by-step explanation:

3x - 8 = -2

3x -8+8 = -2 +8

3x = 6

3x/3 = 6/3

x = 2

s

x - 6

( 2-6)

= -4

that is the value of x -6

= -4
