To solve the problems, we first need to analyze the function \( f(x) = x^2 - 5x + 6 \).

Completing the Statements

1. The solutions to the equation f(x) = 6: To find when \( f(x) = 6 \), we set the equation equal to 6:

\[ x^2 - 5x + 6 = 6 \]

Subtracting 6 from both sides gives us:

\[ x^2 - 5x = 0 \]

Factoring out \( x \) results in:

\[ x(x - 5) = 0 \]

Thus, the solutions are:

\[ x = 0 \quad \text{or} \quad x = 5 \]

Therefore, the points where \( f(x) = 6 \) are \( (0, 6) \) and \( (5, 6) \).

2. The solutions to the equation f(x) = f(2) and f(3): Next, we find \( f(2) \) and \( f(3) \):

Calculating \( f(2) \):

\[ f(2) = 2^2 - 5 \cdot 2 + 6 = 4 - 10 + 6 = 0 \]

Calculating \( f(3) \):

\[ f(3) = 3^2 - 5 \cdot 3 + 6 = 9 - 15 + 6 = 0 \]

Both \( f(2) \) and \( f(3) \) equal 0. This means finding the points where \( f(x) = 0 \).

Returning to \( f(x) = 0 \):

\[ x^2 - 5x + 6 = 0 \]

Factoring gives us:

\[ (x - 2)(x - 3) = 0 \]

Thus, the solutions are:

\[ x = 2 \quad \text{or} \quad x = 3 \]

So, the points where \( f(x) = f(2) \) and \( f(3) \) are \( (2, 0) \) and \( (3, 0) \).

Summary of Answers

  1. The solutions to the equation \( f(x) = 6 \) are the points (0, 6) and (5, 6).
  2. The solutions to the equation \( f(x) = f(2) \) and \( f(3) \) are the points (2, 0) and (3, 0).
