Can Any one solve this?
find the value of x which function is not continuous
a) f (x) = 3x + 1/ x^2 + 7x -2
b) f (x) = 7/x + 3x / x+6
Thanks for ur great help in advance

try and put more brackets in!
not continuous when the denominator = 0,
(a) x^2 + 7x - 2 = 0, so, x = -7/2 +- {sqrt(57)}/2
(b) put over same denominator and find when =0:
7/x + 3x / x+6 = {7(x+6) + 3x^2}/x(x+6)
not continuous when, x=0, x=-6
