Answer by stanbon(75887)   (Show Source):
You can put this solution on YOUR website! graph the function and determine its domain and range.
h(x)=x^2 + 1
----
Plot 3 points since it is a quadratic::
(0,1) ; (2, 5); (-2,5)
---
Draw a parabola thru the 3 points.
----
[[[graph(400,400,-10,10,-10,10,x^2+1)}}}
--------
Domain:: All Real Numbers
Range:: Since the vertex is at (0,1), range = All Real Numbers >= 1.
