1) 3 pts. The graph of a function f is shown below. Are the following statements about f true or false? Why? A. x = a is in the domain of f (x) ? B. limr-a f(x) exists ? c. lim f (z) = lim- f (ac) ?. 2) 3pts. For the function f (ac) = a2 - 5x + 4 Find A. f (a) = B. f ( a t h) = C. flath) - f(a) = h flath) - f(a) 3) 4pts. check other posts, make a meaningful comment. And discuss with others what is the meaning of the limit of h as h ----> 0 at x= a, then at x = b, or any other value of x
