Help me fot this ex.1

Please Read: I do not speak Bulgarian, but if it's looking for coordinates, I'll try to give possible answers that may help you
Expand Answer: [tex]y=x^{2} +4[/tex] = [tex]y= (x+2)(x-2)[/tex]
Answer: [tex]y= (x+2)(x-2)[/tex]
X- intercept(s): Set y to 0 and solve ( [tex]0=x^{2}+4[/tex] , [tex]4=x^{2}[/tex] , [tex]\sqrt{4} =x[/tex], [tex]x= 2, -2[/tex])
Answers: [tex]x= 2, -2[/tex]
Y- intercept: Set x to 0 and solve ( [tex]y= 0^{2}+4[/tex], [tex]y=0+4[/tex], [tex]y=4[/tex])
Answer: [tex]y=4[/tex]

Answer: See attached image
I apologize if this doesn't help you but I tried to list every possible algebraic answer that it would be asking for. Good luck with your mathematics class!
