Solution

The correct option is B
5

When $x = 3$ ,
$x^{2} - 3 x + 5$
$= {(3)}^{2} - 3 \times 3 + 5$
$= 9 - 9 + 5 = 5$

$∴$ The value of the polynomial
$x^{2} - 3 x + 5$ at $x = 3$ is 5.

The value of the polynomial: $x^{2}$ - 3x + 5 at x=3 is

f (x) = x^{3} - 3 x + 5

x = 1.99

∣ ∣ ∣ ∣ \begin{matrix} 3 x + 4 & x + 2 & 2 x + 3 4 x + 5 & 2 x + 3 & 3 x + 4 10 x + 17 & 3 x + 5 & 5 x + 8 \end{matrix} ∣ ∣ ∣ ∣ = 0

x = - 1

f (x) = x^{3} - 3 x + 5

x = 1.99
