Paragraph: Let f(x)=x^2-5 x+6, g(x)=f(|x|), h(x)=|g(x)| . Question: The number of integral values of x satisfying the equation g(x)+|g(x)|=0 is equal to:
Options
- A0
- B1
- C2
- D4
Correct answer
D. 4
Step-by-step solution
h(x)=k will have more than two solutions for k=0,1,2,3,4,5,6 h(x)=k will have exactly 8 distinct solution for 0 < k < 1 4 No integral value of k . Probability =0 Clearly, |g(x)|=-g(x) x [-3,-2] [2,3]
