Question

can someone do this for me i dont get it its confusing me?

Answer 1

To graph the given equation, we need some points .

The given equation is of the form

$y=mx +b$

Where the y intercept is (0,3). And to find the x intercept , we have to plug y=0, and solve for x, that is

$0=-x+3\\x=3$

So the x intercept is (3,0).

So we have (3,0) And (0,3).

On plotting and joining the points we will get the required graph .

Domain, D:

There is no restriction on x. Therefore domain is

$(- \infty, \infty )$

And similarly, Range,R:

$(- \infty, \infty)$
