Question

f(x)=x²-4x+1 find f(1/2)​

Answer 1

f(X) = x^2 - 4x + 1

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

f(1/2) = 1/4 - 1

f(1/2) = -3/4

Answer 2

Given :

• f(1/2)

Solution :-

$f( x) = x {}^{2} - 4x + 1$

$f( \frac{1}{2} ) = ( \frac{1}{2} ) {}^{2} - 4 \times \frac{1}{2} + 1$

$= > \frac{1}{4} - 2 + 1$

$= > \frac{1 - 8 + 4}{4}$

$= > \frac{ - 7 + 4}{4}$

$= > \frac{ - 3}{4}$
