Answer 1

explanation or answer?

Answer 2

explanation plz

Answer 3

i already know the answer

Answer 4

In order for f of x to be differentiable at x=0, the left and right-hand derivatives have to be equal. I think you can just find the derivative of both equations, substitute 0 for x, and solve for a. Then, to find b set the two equations equal to one another (they have to equal the same thing at x=0). Is the answer c?

Answer 5

um yea, it's C.
I didn't do the derivative of both equation. I get it now, thanks!
