1. F(x) = Y = (X-1)^2 - 2.
To graph the function,find 2 points on each side of the vertex:
(-1,2), (0,-1), V(1,-2), (2,-1), (3,2).
Domain: Since there is no denominator that can become zero and cause the function to be undefined, the domain
is all real values of X.
Range: The lowest point on the graph
is the vertex with a Y-coordinate of
-2. Therefore, the range is all values
of Y from -2 to infinity.
