Question

Find the inverse of the function. y = x2 + 4x + 4

Answer 1

Answer:

y = -2+$\sqrt{x}$ and y = -2 - $\sqrt{x}$ combined, or $x = y^2 + 4y + 4$

Step-by-step explanation:

$y = x^2 + 4x + 4$

substitute y for x and x for y

$x = y^2 + 4y + 4$

this is technically the inverse but I will simplify further

x = $(y+2)^2$

±$\sqrt{x}$ = y+2

y = -2±$\sqrt{x}$

y = -2+$\sqrt{x}$ and y = -2 - $\sqrt{x}$ combined
