Solution Steps

Step 1: Identify the function and the value of 'a'

The given function is \( f(x) = \frac{x^2 - 100}{x + 10} \) and \( a = -10 \).

Step 2: Simplify the function

Simplify \( f(x) \) by factoring the numerator: \[ x^2 - 100 = (x + 10)(x - 10) \] So, \[ f(x) = \frac{(x + 10)(x - 10)}{x + 10} \] For \( x \neq -10 \), this simplifies to: \[ f(x) = x - 10 \]

Step 3: Sketch the graph of the function

The simplified function \( f(x) = x - 10 \) is a linear function with a slope of 1 and a y-intercept of -10. However, at \( x = -10 \), the function is undefined. The correct graph should be a line with a hole at \( x = -10 \).

Final Answer

The correct graph is option C.
