Question

Paragraph Let f(x) = 2x^2 - 4px + p^2+ 3p + 2, X e R. If the range of f(x) is to(o , infinite) for every x e R. then the sum of all possible values of p is (A) - 3 (B) 3 (C) 6 (D) 9​

Answer 1

step by step explanation:

f(x)=2x^2-4px+p^2+3p+2

so, f(0) is less than 0

f(0)<0

p^2+3p+2<0

(p+2)(p+1)<0

p belongs to [-2,-1]

so,there are no integral value of p

ANSWER: A(-3)
