Answer:
±sqrt (x-25) = y
Step-by-step explanation:
To find the inverse of a function, exchange x and y and then solve for y
y = x^2 +25
Exchange x and y
x = y^2+25
Now we need to solve for y
Subtract 25 from each side
x-25 = y^+25-25
x-25 = y^2
Take the square root of each side
±sqrt (x-25) = sqrt(y^2)
±sqrt (x-25) = y
