Determine the parameters a and b so that the function is continuous

[Erros]

I did this task with the function and I got the result that a = -1 and b = 3, can someone help me and check if it is a good result or if I got the right solution.

Determine the parameters a and b so that the function is continuous:

Correct. Do you need to show your working?

 

[Erros]

@Harry_the_cat Can you explain this part? How did what I underlined come about? That part is not very clear to me

 

[Harry_the_cat]

The square root sign extends over the 3 and the x^2.

Erros,
Can you please explain how YOU got the correct results even though you used the wrong function?
It is hard to help a student who hides things from us.
