Solution Steps

Step 1: Identify the Function

Consider the function \( f(x) = \frac{7}{x^2 - 49x} \).

Step 2: Factor the Denominator

Factor the denominator: \[ x^2 - 49x = x(x - 49) \]

Step 3: Find Points of Discontinuity

Set the denominator equal to zero to find the points where the function is not defined: \[ x(x - 49) = 0 \] This gives us the solutions: \[ x = 0 \quad \text{and} \quad x = 49 \]

Step 4: Conclusion on Continuity

The function \( f(x) \) is not continuous at the points \( x = 0 \) and \( x = 49 \) because the function is undefined at these values.

Final Answer

The correct answer is C.
The function is not continuous at \( x=0 \) and \( x=49 \).
The reason is D. The function does not exist at the points \( x=0 \) and \( x=49 \) and a small change near these values of \( x \) may produce large changes in \( f(x) \).
