Question

If p(x) = x2-3x+4, then find the value of p (-1).​

Answer 1

Answer:

Step-by-step explanation:

Substituting -1 in place of x

= (-1)^2 - 3(-1) + 4

= +1 + 3 + 4

= 8

Answer 2

Answer:

8

Step-by-step explanation:

Given:- p(x) = $x^{2} -3x+4$

To Find:- Value of above expression when x = -1.

Solution:-  p(x) = $x^{2} -3x+4$

∴ p( -1 ) = $(-1)^{2} - 3(-1)+4$

            = 1 + 3 + 4

            = 8

Hence, the value of expression p(x) = $x^{2} -3x+4$ when x = -1 is 8.
