Answer:
See below
Step-by-step explanation:
For the model function 
, 
is the vertex, and 
is the horizontal growth or shrink factor.
We know that our vertex is 
from our graph, so we'll need to determine the value of by using one of the points on the graph:
Thus, our equation for the given graph is 
.
The domain of a function is the set of all existing real x-values, thus, our domain for the given function is 
, or all real x-values.
The range of a function is the set of all existing real y-values, thus, our range for the given function is 
, or all real y-values starting with y=-1 which is included.
Donc pour trouver la réduction de 30% nous allons trouver 30% de 49 alors nous allons faire 30 × 100 × 49 = 14,7 14,7 est la réduction maintenant nous devons faire 49 € -14,7 € soit 34,3 €, le prix est maintenant de 34,3 €, désolé d'utiliser Google Translate pour vous aider, mais j'espère que c'est correct :)
It's not a function because 4 and 1 has 2 images in y so there's no range but the domain = {4,1,0}
