L = 0.002T + 25, L = cm, T = temperature
State a possible practical domain for the function L(T) = 0.002T + 25

y = (x-4)^2 + 6
having difficulty to find inverse function
For original function we'll take the right branch of the parabola, i.e. x>= 4

First swap x and y
x = (y-4)^2 + 6
(y-4)^2 = x-6
y-4 = +/- sqrt(x-6) but since we took the right arm
y = sqrt(x-6) + 4
