Suppose that the piecewise function f is defined by
1,
f(x) = {√x++ 5x − 4 + √5,
Determine which of the following statements are true.
Select the correct answer below:
O f(x) is not continuous at x = 4 because it is not defined at x = 4.
○ ƒ(4) exists, but f(x) is not continuous at x = 4 because lim f(x) does not exist.
x→4
○ ƒ(4) and lim f(x) both exist, but f(x) is not continuous at x = 4 because lim f(x) ‡ƒ(4).
