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
(switch from y to x and x to y)
I hope that helps!
I got B too so I sure could be right answer but if it's not then I so sorry. B. 6
40+75 x = 125 + 25x
