Question 157422: please helo graph this equation
y = x^2 - 5

You can put this solution on YOUR website!
when x = 0, y = -5
when y = 0, x^2 = 5, so x = sqrt%285%29
set up some points from x = -5 to x = +5
x,y
-5,20
-4,11
-3,4
-2,-1
-1,-4
0,-5
1,-4
2,-1
3,4
4,11
5,20
looks like the graph bottoms out at -5 and goes up symmetrically for every value of +/1 x.
graph would look like this:
