Question

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

Answer 1

f(x) = -(x + 1)^2
f(x) = -(x^2 + 2x + 1)
f(x) = -x^2 - 2x - 1

Answer 2

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

.
