Question

Help me fot this ex.1

Answer 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

Answers:

Expand Answer: $y=x^{2} +4$ =    $y= (x+2)(x-2)$

Answer: $y= (x+2)(x-2)$

X- intercept(s): Set y to 0 and solve  (   $0=x^{2}+4$  ,      $4=x^{2}$ ,       $\sqrt{4} =x$, $x= 2, -2$)

Answers: $x= 2, -2$

Y- intercept: Set x to 0 and solve (   $y= 0^{2}+4$,         $y=0+4$,         $y=4$)

Answer: $y=4$

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!
