Question

If f(x) = x2 -2x + 3. Then f(-2) is​

Answer 1

Answer:

Explanation:

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

                           = -4 + 7 = 3

Answer 2

Answer:

11 is the required value of $x^2 -2x +3$.

Explanation:

Given in the question that, f(x) = $x^2 -2x +3$

According to the question we need to find out the value of f(-2).

On putting the value of x  = -2 we get,

⇒$x^2 -2x +3$

⇒$(-2)^2 -2(-2) +3$

Where $2^2 = 4$ and (-×-) = +

⇒4 +4 + 3

⇒8 +3

⇒11.

Final answer:

Hence, the value of f(-2) is 11.
