Answer:
(x-3)^2
Step-by-step explanation:
y = sqrt(x) +3
To find the inverse , we exchange x and y and then solve for y
Exchange x and y
x = sqrt(y) +3
Now solve for y
Subtract 3 from each side
x-3 = sqrt(y)
Square each side
(x-3)^2 = (sqrt(y))^2
(x-3)^2 = y
The inverse of sqrt(x) +3 is (x-3)^2
f⁻¹(x) = (x-3)² is the inverse of given function.
We have given function:
f(x) =√x +3
W e have to find the inverse of the given function.
Let y = f(x) then
y = √x +3
First, we interchange x and y we get,
x =√y +3
then solve the above equation for y we get,
√y = (x-3)
Squaring both sides we get,
y= (x-3)²
Replacing y to f⁻¹(x) we get,

Yes, they are equivalent.
I think it's B.)
(350x2=700) + (125x2=250) 700+250=950 so the perimeter is 950 meters long I hope this helps!
