graphs below to determine whether the function is continuous at a point or not. 3. f(x) = at x = -1 5 / 19 4. g(x) = 242 at x = -2 5. h(x) = 1-1 _great x = 4 KEY CONCEPT EXAMPLE 1: Draw the graph of the function f(x) = x - 7 to determine whether the function is continuous at x = 4 or not. 6 / 19 The graph shows that f(x) = x - 7 is continuous at x = 4. EXAMPLE 2: Draw the graph of the function g(x) = = to determine whether the function is continuous at x = 3 or not. The graph shows that g(x) = = is discontinuous at x = 3
