The graphs given alongside represent two functions \(f(x)\) and \(g(x)\) respectively. Which of the following is true?
Step 1: Analyze the graphs
From the left graph (for \(f(x)\)):
Looks like a “V”-shaped graph opening upward → Suggests \(f(x) = |x|\) From the right graph (for \(g(x)\)):
“V”-shaped graph opening downward → Suggests \(g(x) = -|x|\)
Step 2: Compare definitions If \(f(x) = |x|\), then clearly: \[ g(x) = -|x| = -|f(x)| \Rightarrow g(x) = -|f(x)| \] % Final Answer: (c)
Let A be the set of 30 students of class XII in a school. Let f : A -> N, N is a set of natural numbers such that function f(x) = Roll Number of student x.
On the basis of the given information, answer the followingIs \( f \) a bijective function?
