How do check the graph of a function has an infinite discontinuity at a point or not? (without the help of a graphing calculator)
example: Check whether y = (x^2-9)/(3x-9) has an infinite discontinuity at x = 3 or not
CAn you get rid of the denominator?
(x+3)(x-3)/3(x-3) in the limit at x=3, this becomes 2.
