Question

If f(x) = x..........

Answer 1

Step-by-step explanation:

`f(x) = {x}^(2) - 2x + 1`

`f(x) = {(x - 1)}^(2)`

`g(x) = x + 2`

`\:`

`= f(g( - 1))`

`= {(x - 1)}^(2)`

`= {((x + 2) - 1)}^(2)`

`= {(( - 1 + 2) - 1)}^(2)`

`= {(1 - 1)}^(2)`

`= {0}^(2)`

`= 0`

The answer is B.

Answer 2

b.) 0

Step-by-step explanation:

⇒ f(g(-1))

go from right to left while solving such function questions.

⇒ f(-1 + 2)

⇒ f(1)

⇒ (1)² -2(1) + 1

⇒ 0
