Evaluate the function if f(x)=x²-2x+1. Find f(-1+√2)

Can someone help me please?​

6 - 4

Step-by-step explanation:

To evaluate, substitute x = - 1 + into f(x)

f(- 1 + )

= (- 1 + )² - 2(- 1 + ) + 1 ← expand squared factor using FOIL

= 1 - 2 + 2 + 2 - 2 + 1 ← collect like terms

= 6 - 4

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
