please help me solve these

(1 point) Shown below are six statements about functions. Match each statement to one of the functions shown below which BEST matches that statement. 1. lim,-6+ f(x) and limx-6- f(x) both exist and are finite, but they are not equal. 2. The graph of y = f (x) has vertical tangent line at (6, f(6)) 3. lim, -6- f(x) = -00. 4. lim,-6+ f(x) exists but limx -6- f(x) does not. 5. limx-6 f(x) = co. 6. lim,-6 f(x) exists but f is not continuous at 6. cos () if x 6 3x if x 6 c. f(x) = x-6 D. f (x) = (x-6)2 E. f(x) = Vx - 6 3x if x 6(1 point) Let f (x) = - 7x - 21 x4 - 8x3 + 16x2 Find each point of discontinuity of f, and for each give the value of the point of discontinuity and evaluate the indicated one-sided limits. If needed, use 'INF' for co and '-INF' for -co. If you have more than one point, give them in numerical order, from smallest to largest. If you have extra boxes, fill each in with an 'x'. Point 1: C = lim f(x) = x-C lim f(x) = xact Point 2: C = lim f(x) = x-C lim f(x) = x-C Point 3: C = lim f(x) = x-C lim f(x) = X-C
