Question

The minimum of a parabola is located at (–1, –3). The point (0, 1) is also on the graph. Which equation can be solved to determine the a value in the function representing the parabola?

Answer 1

✦ Explanation ✦

☛ We know that (-1,-3) is the vertex. 
☛ Set up the parabola as y = k(x+1)²-3
☛ 1 = k(0+1)²-3
☛ k = 4
☛ y = 4(x+1)²-3 is the equation
