The domain is the set on which the function is defined, as division by
zero is not allowed the function is not defined when
as is zero.
When we may write:
which may take any value from and upwards, so the range is:
So the graph of the function is identical to they of except that there
is a hole at

First the domain of this function is all of as it is defined for all real numbers.
As the smallest value that can take is and there is clearly no largest value that it can take. So its range is .
To sketch this we can rewrite the function as:
So the graph is these two line segments with a join at
RonL
Here is graph for F(x)=3x+2.

To repeat what Captain Black said . . .
We see that .

Since , we have: .
We have a parabola, , with a "hole" at (2,4).Code:

We know that the graph of is a with its vertex at the origin.
The graph of is the same but it "rises faster".
The graph of

The graph looks like this:Code:\  /
