What is the sum of x^ 2 – 3x + 7 and 3x² + 5x – 9?
1) 4x² – 8x + 2
2) 4x² + 2x + 16
3) 4x2 – 2x – 2
4) 4x² + 2x - 2

4.

Step-by-step explanation:

To add these two equations together, you have to combine like terms.  

1.

2.

3. 7 - 9 = -2

Then you just combine all of these terms together into one equation and you have your answer.

Hope this helped!

domain is all the x values included in the

0 ≤ x ≤ 2

range is all the y values of the graph

-2 ≤ y ≤ 2

***keep in mind that there are different ways to show domain and range

hope this !
