Answer:
See explanation.
Step-by-step explanation:
5. a. f(5)=-5+5.5
f(5)=0.5
b. 1/(x-3) ==> x-3=0. x=3. f is discontinuous at x=3.
c. A removable discontinuity is when a function is discontinuous at a point, but when x approaches that point, there is a value for x. A nonremovable discontinuity is when the limit doesn't exist.
