Which equation is the inverse of 2(x-2)squared=8(7+y)
dsp73

Answer:

f^{-1}(x)=2(+/-)2\sqrt{(7+x)}

Step-by-step explanation:

we have

2(x-2)^{2}=8(7+y)

step 1

Exchange x for y and y for x

2(y-2)^{2}=8(7+x)

step 2

isolate the variable y

(y-2)^{2}=4(7+x)

take the square root both sides

y-2=(+/-)\sqrt{4(7+x)}

y=2(+/-)\sqrt{4(7+x)}

step 3

Let

f^{-1}(x)=y

f^{-1}(x)=2(+/-)\sqrt{4(7+x)}

f^{-1}(x)=2(+/-)2\sqrt{(7+x)}  ----> equation of the inverse
