Evaluate y = x² Function: Finding Point at x = 11

To solve this problem, we will calculate the value of $y$ for the given function $y = x^2$ when $x = 11$.

Here are the steps to find the solution:

• Step 1: Substitute $x = 11$ into the function equation.
• Step 2: Calculate $y = 11^2$.

Let's work through these steps:

Step 1: By substituting $x = 11$, the function becomes $y = 11^2$.

Step 2: Calculate the value:

$11^2 = 11 \times 11 = 121$

Therefore, for $x = 11$, the value of $y$ is $121$, meaning the point $(11, 121)$ does exist on the function $y = x^2$.

The correct answer from the given choices is $y = 121$, which corresponds to choice id "3".
