Hmm are you sure it's -76? Or is it suppose to be 75?
I get a=-3 if its a 75.. hmm
Sec ill check my work, then I can hopefully explain how i got there.

Here is a little example.
In order for this piece-wise function be continuous, the limit from the left, needs to EQUAL, the limit from the right (approaching -5).
That's why I drew those little arrows, to show that we're approaching -5 from each side.
Also, their tangent line's need to be approaching the same value at that point -5.
Meaning, their derivatives must be equal when approaching from the left and right.
So we have a little bit of work to do.
And it will give us a system of 2 equations, and we'll be able to solve for a and b from there.

And from here, you have a system of equations and should be able to solve for a and b!! :)
If you're stuck on how to solve the system, you can let me know.
