Question

Find the discontinuities (if any) of each function
1. f(x) = 1/(x-4)
If there is point(s) of discontinuities then x = , x =
2. f(x) = 3/(x+3)
If there is point(s) of discontinuities then x = , x =

Answer 1

discontinuities occur when f(sx is undefined
division by zero is undefined.
where is the denominator zero?
