Step-by-Step Solution

To solve this problem, we'll determine where the graph of the function intersects the x-axis by following these steps:

  • Step 1: Set the function equal to zero: y=(x6)(x5)=0 y = (x-6)(x-5) = 0 .
  • Step 2: Solve for the x-values where the equation equals zero.
  • Step 3: Express these x-values as points where y y is zero, representing the intersections with the x-axis.

Now, let's apply these steps:

Step 1: Set the equation to zero: (x6)(x5)=0 (x-6)(x-5) = 0 .

Step 2: Solve for x x .

  • Set the first factor to zero: x6=0 x-6 = 0 . Solving for x x gives x=6 x = 6 .
  • Set the second factor to zero: x5=0 x-5 = 0 . Solving for x x gives x=5 x = 5 .

Step 3: The solutions represent points on the x-axis where the function intersects.

Thus, the points of intersection are (6,0) (6, 0) and (5,0) (5, 0) .

Therefore, the solution to the problem is (6,0),(5,0)(6,0),(5,0).

Answer

(6,0),(5,0) (6,0),(5,0)
