Question

If f(x) is a quad polynomial such f(2)=-3amd f(-2)=21 then coffee of x in f(x) ​

Answer 1

Answer:

here u go

Step-by-step explanation:

Let f(x) = ax2 + bx + c

Given, f(2) = -3

This gives 4a + 2b + c = -3        ... (1)

 

Given, f(-2) = 21

This gives 4a - 2b + c = 21        ... (2)

 

Subtracting (2) from (1), we get,

4b = -24

b = -6

 

Thus, the coefficient of x in f(x) is b = -6.

Answer 2

Answer:

options which is correct is -6
