Step-by-Step Solution

To solve this problem, we'll determine the intersection points of the function y=(x1)(x1) y = (x - 1)(x - 1) with the x-axis by following these steps:

  • Step 1: Set the function equal to zero to find where it intersects the x-axis.
  • Step 2: Solve the equation (x1)2=0(x - 1)^2 = 0.
  • Step 3: Determine the x-coordinate(s) from this equation.
  • Step 4: The y-coordinate will be zero at these points.

Let's work through these steps:

Step 1: We set the given function to zero: y=(x1)2=0 y = (x - 1)^2 = 0 .

Step 2: By solving the equation (x1)2=0(x - 1)^2 = 0, we apply the property that a square is zero only if the base is zero.

Step 3: Solving (x1)=0(x - 1) = 0, we find:

x=1 x = 1

Step 4: The corresponding point on the graph is (1,0)(1, 0), indicating where the function crosses the x-axis.

Therefore, the point of intersection of the function with the x-axis is (1,0) (1, 0) .

Answer

(1,0) (1,0)
