Question 109721
what is the range for the graph of y=-x^2+5, and how do i write that in interval notation?
----------------------------
{{{graph(400,300,-10,10,-10,10,-x^2+5)}}}
-----------------
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]
