You can put this solution on YOUR website! Hi I need to graph the following quadratic equations:
y=x^2+2x+5
--------
The low point where x = -b/(2a) = -2/(2) = -1
------
f(-1) = 1-2+5 = 4 giving you the low point (-1,4)
f(0) = 0+0+5 = 5 giving you the point (0,5)
f(-2) is symetric so have the point (-2,5)
---
Plot those points and draw a parabola thru them::
----------
Cheers,
Stan H.
