Explain how to graph the following function and determine its domain and range
y=-x^2+4-7 ​

Domain is: ( − ∞ , ∞ ) ,  { x | x ∈ R }

range is: ( − ∞ , − 3 ]  ,  { y | y ≤ − 3 }

Graph the parabola using the direction, vertex, focus, and axis of symmetry.

Step-by-step explanation:

3 is greater then both of those numbers
