Step-by-Step Solution

To solve this problem, we'll need to determine where the function intersects the x-axis, which occurs where y=0 y = 0 .

Let's work through the solution:

  • Step 1: Set the function equal to zero: x(x1)=0 x(x-1) = 0 .
  • Step 2: Apply the zero-product property, which states that if the product of two numbers is zero, at least one of the factors must be zero.
  • Step 3: Set each factor equal to zero: x=0 x = 0 or x1=0 x - 1 = 0 .
  • Step 4: Solve for x x in each equation:
    - For x=0 x = 0 : This immediately gives us the solution x=0 x = 0 .
    - For x1=0 x-1 = 0 : Add 1 to both sides to get x=1 x = 1 .

Therefore, the two points of intersection with the x-axis are (0,0) (0,0) and (1,0) (1,0) .

This matches with choice 2, thus confirming the correct option.

Thus, the points of intersection with the x-axis are (0,0) (0,0) and (1,0) (1,0) .

Answer

(0,0),(1,0) (0,0),(1,0)
