#4: The following limit represents the derivative of some function fat some number a. Find such an f and a. Lim V49 + h - 7 h (A) f(x) = Vx, a=7 (B) f(x) = Vx, a= 7 +h (C)f(x) = Vx+h - 7, a= 49 (D)f(x) = Vx, a= 49 +h (E) f (x) = Vx - 7, a=7 (F) f(x) = Vx+h, a=49 (G)f(x) = Vx+ h, a=7 (H)f(x) = Vx, a=49#3: Consider the function 12 -1 P(1) = 2 _ 71+6 (a) For what value of t does P(t) have a removable discontinuity (also called a hole)? (b) For what value of t does P(t) have an infinite discontinuity (also called a vertical asymptote)
