Which function has a removable discontinuity at x = 7?

9514 1404 393

  (b)  see below

Step-by-step explanation:

A removable discontinuity exists when the function is undefined at a point where the limit exists.

Choices A, C, D have no limit at x=7 (does not exist).

__

Choice B can be simplified to ...

  f(x) = (x -3)(x -7)/(x -7)

  f(x) = (x -3) . . . . . . . x ≠ 7 (domain restriction; undefined at x = 7)

The discontinuity in this function can be removed by defining the function to be f(x) = x-3 everywhere.

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
