Question

The value of polynomial f(x) = 5x−4x²+3 when x = -1, is

Answer 1

Step-by-step explanation:

f(1)=5(-1)-4(-1)(-1)+3=-5-4(1)+3=-5-4+3=-9+3=-6

Answer 2

Answer:

To Find the value of polynomial at x = -1 or F(-1)

So we will put x = -1 in polynomial

$F(-1) = 5 × (-1) - 4× (-1)²+3$

$= -5 - 4 + 3$

$= -6$

So value of polynomial of x = - 1 is -6
