   2. Graph the functions \[y=x\] and \[y=\sqrt{x}\] on the same graph (by plotting points if necessary). Show the points of intersection of these two graphs.
      
      Graph
      
      c) How does the graph relate to part a?
      Answer: The intersection between the two graphs gives the solutions of the equation \(x-\sqrt{x}=0\).
      
4. A right triangle is a triangle with one angle measuring 90°. In a right triangle, the sides are related by Pythagorean Theorem, \[{{c}^{2}}={{a}^{2}}+{{b}^{2}}\] where c is the hypotenuse (the side opposite the 90° angle). Find the hypotenuse when the other 2 sides’ measurements are 3 feet and 4 feet.
