Find the point of discontinuing of the given function: 2 Marks
f (x) = 3x + 1
I assume it is
3x + 1
Factor the denominator into factors. Anytime the denominator becomes zero, there will be a discontinuity in the function, since the function at these points will be undefined (division by zero is not allowed).
The denominator factors to (x-3)(x-4) and therefore will have 2 positive roots.
Can you find them?
