Answer :
Answer:
y = -2+[tex]\sqrt{x}[/tex] and y = -2 - [tex]\sqrt{x}[/tex] combined, or [tex]x = y^2 + 4y + 4[/tex]
Step-by-step explanation:
[tex]y = x^2 + 4x + 4[/tex]
substitute y for x and x for y
[tex]x = y^2 + 4y + 4[/tex]
this is technically the inverse but I will simplify further
x = [tex](y+2)^2[/tex]
±[tex]\sqrt{x}[/tex] = y+2
y = -2±[tex]\sqrt{x}[/tex]
y = -2+[tex]\sqrt{x}[/tex] and y = -2 - [tex]\sqrt{x}[/tex] combined
