Answer 5

A polynomial function has no restrictions on x. Any real number can be used as x.
The domain is all real numbers.

For the range, you need to see which y values are valid.
Graph the function, or use technology to graph the function and see what the lowest y value is.

Answer 6

Once I do that, I'll let you know what I get.

Answer 7

@mathstudent55 I graphed the function, and I got the coordinates of (0,3) and (1,2)

Answer 8

The y values would be 2 and 3.

Answer 10

What is the lowest y-coordinate in the graph of the function?

Answer 11

2?

Answer 12

Yes.
That means the range is all real number, 2 or higher.

Answer 13

So, the answer would be A?
