Let (f:[-2,2]\to[0,4]), where (f(x)=x^2). Which statement is correct about (f)?

Answer and explanation

Correct answer: Onto but not one-one

Step 1: On ([-2,2]), the range of (x^2) is ([0,4]). Step 2: The codomain is the same, so it is onto, but (f(-1)=f(1)), so it is not one-one. Step 3: Even functions often give equal outputs for different inputs.
