Question

find f(√2), if f(x) = x^2 + √2x +1 pls answer quickly​

Answer 1

Answer:

I don't know please ask any questions

Answer 2

Answer:

f(x)=x^2+2x+3

f(2x-1)= (2x-1)^2 +2(2x-1)+3

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

x^2+2x+3 =(2x-1)^2+2(2x-1)+3

or x^2+2x =4x^2–4x+1+4x-2

or x^2+2x=4x^2–1

or 3x^2–2x-1 =0

or 3x^2–3x+x-1=0

or 3x(x-1)+1(x-1)=0

or (x-1) (3x+1) =0

x = 1 , -1/3 , Answer.
