49 Let f(x) = T - 3 (a) (1 point) Evaluate lim f(x) or state that it does not erist. (b) (1 point) Is f continuous at x = 3? (c) (4 points) Use the limit definition of the derivative to find f'(10) for the function f. No credit will be given unless the limit definition is used. Simplify and double check your
