Let `A="{"-1,0,1")"a n df={(x , x^2): xA}dot` Show that `f: AvecA` is neither one-one nor onto.

Explanation

To show that the function \( f: A \to A \) defined by \( f(x) = x^2 \) is neither one-one nor onto, we will follow these steps:

### Step 1: Define the Set A and the Function
Let \( A = \{-1, 0, 1\} \) and the function \( f(x) = x^2 \) for \( x \in A \).

### Step 2: Calculate the Function Values
We will calculate the function values for each element in the set \( A \):
- For \( x = -1 \):
