Answer:
x = y^2 + 4y + 3
Step-by-step explanation:
f(x) = ( x + 2 )^2 - 1
y = ( x + 2 ) ^ 2 - 1
y = ( x^2 + 4x + 4 ) - 1
y = x^2 + 4x + 4 - 1
y = x^2 + 4x + 3
x = y^2 + 4y + 3
(switch from y to x and x to y)
I hope that helps!

More than one unique triangle. All triangles are equal to 180, so a triangle with these measures CAN exist. It can also exist in multiple sizes.
First, see if you can subsitute 5 for x and get a real number
if x=5 then we get 5^2+2=25+2=27
