Below are functions f(x) which is blue, g(x) is green and h(x) is purple. Click and slide the red diamond to change the value of x. As x changes the values of each of the functions is updated. Try sliding the diamond and observe how the function values change. 1. Find f(2), g(2), and h(2). This means, evaluate f(x), g(x) and h(x) when x = 2. 2. Find f(3), g(3), and h(3). 3. Find f(0), g(0), and h(0). 4. Find f(-1), g(-1), and h(-1). 5. Find x when g(x) = 9. 6. Find h(x) when g(x) = 9.
