Answer:
traingular Number Sequence: 1, 3, 6, 10, 15, 21, 28, 36, 45, .etc.
Answer: option d.
Step-by-step explanation:
To create a table of five ordered pairs that satisfy the equation, you need to give values to the variable "x" and substitute these into the function to find the corresponding value of "y":
For 

For 

For 

For 

For 

Then, you can make the table:
<em><u>x</u></em><u> </u><u>-2 -1 0 1 2</u>
<em><u>y </u></em><u> </u><u>9 7 5 3 1</u>
To find the x-intercept, substitute
into the function and solve for "x". Then:

This is: (
, 0)
To find the y-intercept, substitute
into the function and solve for "y". Then:

This is: (0,5)
Y=-4 is linear, anything not linear would be a quadratic in this instance
