Hi, I want to know the answer to question 2 (a-c) with a detailed explanation. Thank you so much

Question 2 Below is a graph representing part of the crosssection of Mount Arbour. The y-axis represents the vertical height (in metres), above the base of the mountain. The xaxis represents the horizontal distance (in metres), from the origin. Mount Arbour 1000 2000 3000 4000 3) Write a hybrid function f(x) to represent the graph of Mount Arbour. b) Hence, state the steepest gradient for Mount Arbour. Thus, if a ski run is constructed on top of Mount Arbour, state the most appropriate run classication (Beginner, Intermediate, or Expert). Base your recommendation on the classication range calculated in Question 1. c) Assuming the entire mountain is used to make a ski run, what is the length of the min, to the nearest metre? Hint: Use your knowledge of Pythagoras' Theorem and right-angle triangles to help find the lengths of the angled sections.

The x-axis represents the horizontal distance (in metres), from the origin. Mount Boston
