Answer:

Step-by-step explanation:

To find the value of the polynomial 5x - 4x² + 3 at different values of x, we substitute the given values into the polynomial expression.

(i) For x = 0:

5(0) - 4(0)² + 3 = 0 - 0 + 3 = 3

So, when x = 0, the value of the polynomial is 3.

(ii) For x = -1:

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

So, when x = -1, the value of the polynomial is -6.

(iii) For x = 2:

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

So, when x = 2, the value of the polynomial is -3.

Therefore, the values of the polynomial 5x - 4x² + 3 at x = 0, x = -1, and x = 2 are 3, -6, and -3, respectively.
