Question

If f(x) = 2x2 + bx + c and f(0) = 3 and f(2)= 1,
then f(1) is equal to
(A) -2 (B) 0 (C) 1 (D) 2
(A)​

Answer 1

Answer:

f(1)=0

Step-by-step explanation:

f(x)=2x^2+bx+c

given f(0)=3

put x=0 in equation

f(0)=2(0)+b(0)+c

3=c

so c=3

put x=2 in equation

f(2)=2(2)^2+b(2)+c

1=2(4)+2b+3

1=11+2b

1-11=2b

-10=2b

15=b

so b=-5

now f(1)=2(1)^2+b(1)+c

=2+(-5)+3

=5-5

=0

so f(1)=0
