e) the cross section pictured in part a) is just one half of green hill. The left hand side of the hill given as function g(x) , can be found by reflecting the function f(x) in the y-axis . Give the equation for g(x) , including its domain . F) looking at the functions g(x) and f(x) , state the limitation of using these functions to model the side of a hill. What assumptions have been made that may affect the reasonableness of your solution ?

Below is a graph representing part of the cross-section of Green Hill. A road called Hillside Road follows the path shown. The y-axis represents the vertical height in metres, above the base of the road. The x-axis represents the horizonta! distance in metres from the origin. Hillside Road
