Determine whether a function is continuous or discontinuous.
Determine whether the function
is continuous at x= -4. Start with the first condition of the continuity test. The function is not defined at x = -4 because substituting -4 for x results in a denominator of zero. So the function is discontinuous at x = -4.
2. Determine whether each function is continuous at the given x-value. Justify your response using the continuity test.
