How do you find the domain and range of #f(x)=(x-1)^2 +2#?
1 Answer
The domain is all real numbers
The range is
Explanation:
The easiest way to find the domain and range of a quadratic function is to look at the graph.
The general equation of a parabola in vertex form is
A positive
The vertex of this example is then
The domain is found by considering all the possible values of
Looking at the graph, you can see that
The range is found by considering all the possible values of
There are no values of
graph{(x-1)^2+2 [-10.12, 9.88, -2.4, 7.6]}
