Parabola
Investigate the effect of the values h and k i the function f(x) = (x - h)² + k
1. Drag the k slider and describe the effect k has on the position and the shape of the graph. 2. State the coordinates of the vertex, when k = -4, -2, 0, 2 and 4. Reset the graph window. 3. Drag the h slider and describe the effect h has on the position and the shape of the graph. 4. State the coordinates of the vertex, when h = -4, -2, 0, 2 and 4. Make a general statement regarding the shape and position of the graphs compared to f(x) = x²
