what is the range for the graph of y=-x^2+5, and how do i write that in interval notation?
----------------------------
graph%28400%2C300%2C-10%2C10%2C-10%2C10%2C-x%5E2%2B5%29
-----------------
Range:
The highest value of -x^2 is zero
The highest value of -x^2+5 is 5
Range is "All Real numbers less than or equal to 5"
Interval Notation: (-inf,5]
