Step-by-Step Solution

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

  • Step 1: Identify the given function and required y-value.
  • Step 2: Attempt to solve x2=6 x^2 = -6 for x x .
  • Step 3: Conclude based on the results of the equation.

Let's work through each step:

Step 1: The function we are dealing with is y=x2 y = x^2 , and we need to find x x such that y=6 y = -6 .

Step 2: Substitute 6-6 for y y, which gives us:

x2=6 x^2 = -6

Step 3: To solve x2=6 x^2 = -6 , consider whether it is possible for a real number squared to equal a negative number. A critical point here is that the square of any real number is non-negative. Therefore, there is no real value of x x that satisfies x2=6 x^2 = -6 .

Thus, there is no point where y=6 y = -6 for the function y=x2 y = x^2 .

The correct answer is No.

Answer

No
