Calculate y = x² When x = 12: Function Evaluation Practice

To solve this problem, we'll follow these steps:

• Step 1: Identify the given information.
• Step 2: Apply the appropriate formula by substituting the given value.
• Step 3: Perform the calculation to find the solution.

Let's work through each step:

Step 1: The function is given by $y = x^2$ and the value of $x$ is 12.

Step 2: Substitute $x = 12$ into the function. We have:

$y = 12^2$.

Step 3: Calculate the square of 12:

$12^2 = 144$.

Therefore, the value of $y$ at the point $x = 12$ is $y = 144$.

Comparing this with the multiple-choice answers, the correct choice is:

• Choice 4: $y = 144$.

Thus, the final answer is $y = 144$.
