Find the point of discontinuing of the given function: 2 Marks
f (x) = 3x + 1
X2-7x+12

  • calculus -

    I assume it is
    f (x)
    3x + 1
    =--------
    x²-7x+12

    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?
