2: Determine which function is linear and which function is quadratic. How did you know which one is quadratic? a) b) The graph of a quadratic function is a parabola. To graph quadratic equations, we can use the vertex form for the equation of a parabola , where (h,k) is the vertex of the parabola. Question 3: If graph the basic quadratic function , how does "h" affect the graph? What happens when h is positive and h is negative? What should we be careful of when determining h from the vertex form of the parabola? (hint: when is sign positive and when negative) Question 4: If graph the basic quadratic function , how does "k" affect the graph? What happens when k is positive and k is negative? Question 5: If graph the basic quadratic function , how does "a" affect the graph? What happens if a is positive and if a is negative? What happens when a is bigger than 1 and when a is a fraction between 0 and 1? Factor f(x) from part b in question 2. Question 6: What is the value of a, h and k in this quadratic function? When we looked
