Answer:
Step-by-step explanation:
This parabola is a horizontal one.
In the more familiar case, vertical parabolas, the applicable equation is:
y - k = a(x - h)^2, where (h, k) is the vertex and 'a' has to do with vertical compression or stretching.
For the horizontal parabola, we adapt the above formula to:
x - h = b(y - k)^2
substituting -17 for x and 2 for k:
x + 17 = b(y - 2)^2
Because the parabola opens to the left, b must be negative. One of many examples would be:
x + 17 = -2(y - 2)^2, where the choice of 'b' is arbitrary.
