Hi, this is my first post, and I don't want to seem too desparate but I really need help with a problem that I have been unable to do (I've been working on it for close to 2 hours).(adsbygoogle = window.adsbygoogle || []).push({});

If function f(x) is continuous and differentiable and

f(x) = ax*x*x – 6x when x is less than or equal to 1

f(x) = bx*x + 4 when x is greater than 1

then a = ?

(ax*x*x meaning a * x-cubed, etc.)

Anyways, I know that I'm not supposed to ask for a full solution, but I have been unable to do this problem for a very long time, and any help is appreciated (even a full solution).

Thanks for any help.
