Calculate and plot the total magnetic field intensity under a 500 kv transmission line. the balanced three-phase 500 kv transmission line phase conductors are arranged vertically at the same horizontal coordinate x0 = 15 ft. the phase conductors carrying 1000 a are located at heights of 80, 110, and 140 ft from ground level. determine the maximum h value at 1 m above ground level.

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
