Determine whether the function is continuous at the given point c. If the function is not continuous, determine whether the discontinuity is removable or nonremovable. X 9) f(x) ; c=10 X-10 A) Discontinuous; removable, define f(10) = 10 C) Discontinuous; nonremovable Find numbers a and b, or k, so that f is continuous at every point. 10) f(x) = { 4x + 7, if x <-4 kx + 10, if x ≥ -4 A) k = 1 B) k=- 5 N/O B) Discontinuous; removable, define f(10) = 20 D) Continuous C) k=- 19 4 D) k = 5 2
