If f(x) = ax^2 if x<1, and xb if x>1 How do I figure out the values of a and b ? Is it any values that make the f(x) value different when x is approached from the left or the right?

If the function is continuous at , then has the same value "from both sides." From the left:[color=beige] .[/color] From the right:[color=beige] .[/color] If they are equal:[color=beige] .[/color]
