Answer:
Step-by-step explanation:
I believe you meant y = f(x) = a(x - h)^2 + k. This is the vertex form of the equation of a vertical parabola (vertex is located at (h, k) ).
We start with the simplest vertical parabola, y = x^2. This parabola has its vertex at the origin, (0, 0).
13. Translated 2 units left and 7 units down: Substitute -7 for k and -2 for h:
y - (-7) = a (x - (-2) )^2, or (in simpler form), y + 7 = a(x + 2)^2
14. Translated 5 unit right, 2 units up, and stretched by a factor of 3.
Substitute 5 for h and 2 for k, and let z = 3:
y - 2 = 3(x - 5)^2
