I need this answered as soon as possible please

y={(x^2-4)/(x-2) if x is less than 2

{ax^2-bx+3 if x is greater than and equal to 2 and less than 3

{2x-a+b if x is greater than and equal to 3

find a and b

I have done some work and found that a=(-3/2) and b=(-7/2) but this does not work for the continuity at the point x=3

please help

Thank you
