# Find the value of the polynomial $$5x - 4x^2 + 3$$ at : i) x = 0 ii) x = -1iii) x = 2

Let f(x) = $$5x - 4x^2 + 3$$

i)The value of f(x) at x = 0 is :

$$= 5(0) - 4(0)^2 + 3$$
$$= 3$$

$$\therefore$$ f(0) = 3.

ii)The value of f(x) at x = -1 is :

$$= 5(-1) - 4(-1)^2 + 3$$
$$= -5 - 4 + 3$$
$$= -6$$

$$\therefore$$ f(-1) = -6.

iii)The value of f(x) at x = 2 is :

$$= 5(2) - 4(2)^2 + 3$$
$$= 10 - 16 + 3$$
$$= -3$$

$$\therefore$$ f(2) = -3.
