x = a (y - k)2 + h Because the example parabola opens vertically, let's use the first equation. Next, substitute the parabola's vertex coordinates (h, k) into the formula you chose in Step 1. Since you know the vertex is at (1,2), you'll

Simply draw the cube first, then use the angles of the cube to make the curves. 2 Make it using yarn or string. This is even cooler than doing it on

5 = a (1) + 3. 2 = a. To finish, we rewrite the pattern with h, k, and a: 2. Find the equation of the parabola: This is a vertical parabola, so we are using the pattern. Our vertex is (-4, -1), so we will substitute those numbers in for h and k: Now
